Electrostatics

The metal slab will act as a conductor and redistribute the charges to cancel out the electric field inside the slab. As a result, the electrostatic force between the two charges will decrease, since the presence of the metal slab will weaken the field between the charges.

Imagine a light bulb in the center of a sphere. It emits a fixed quantity of light. That's how much light will reach the sphere. The concentration of light per unit of area, on the sphere, will depend upon how large the sphere is. And the area of a sphere is proportional to the square of the radius of the sphere. So the intensity of the light will be inversely proportional to the square of the distance which it has to travel. It is effectively illuminating a larger sphere (even if there is no actual sphere, the principle remains the same).

When a rubber balloon is rubbed against wool, the balloon gains electrons from the wool due to the friction between the two materials. This transfer of electrons causes the balloon to become negatively charged while the wool becomes positively charged. The balloon will then be attracted to positively charged objects and can even stick to them momentarily due to this electrostatic force.

Static electricity builds up in an object when there is an imbalance of positive and negative charges on its surface. This can happen through friction, where electrons are transferred between the objects, causing one to become positively charged and the other negatively charged.

It is logical to say that the potential of an earth-connected object is zero because the earth is a large reservoir of charge that can absorb or supply an infinite amount of charge. When an object is connected to the earth, the charges on the object will redistribute until the potential of the object is the same as that of the earth, which is considered zero.

Some common examples of static electricity include rubbing a balloon on hair to make it stick, shuffling feet across a rug and then getting a shock from touching a metal object, and seeing clothes cling together after being in the dryer.

No, a hollow sphere can hold a larger electric charge compared to a solid sphere of the same diameter because the charge resides on the outer surface in both cases. In a hollow sphere, the charge distributes uniformly on the outer surface, allowing it to hold more charge without experiencing as much repulsion between like charges as a solid sphere.

Yes, the amount of rubbing can impact the amount of static electricity generated on a balloon. Rubbing creates friction between the balloon and the material rubbed against, causing the transfer of electrons and building up static charge on the balloon. More rubs can result in a stronger static charge.

An electrostatic transducer converts electrical energy into mechanical energy, often used in speakers and headphones to produce sound.

The electrostatic series is a way to determine the relative tendencies of materials to gain or lose electrons when they come into contact with each other. By referencing the electrostatic series, you can predict which material will become positively charged and which will become negatively charged during friction or contact. This information is useful in scenarios where static electricity needs to be controlled or minimized.

The direction of the dipole moment of an electric dipole from negative to positive charge is chosen as a convention to align with the direction of the electric field produced by the dipole. This convention allows for easy calculation and understanding of how the dipole interacts with external electric fields.

Yes, when a jumper is rubbed against a balloon, electrons can transfer between the two surfaces. This can result in a net imbalance of charge on the surfaces, with the jumper becoming either positively or negatively charged depending on the direction of electron transfer.

A minimum of about 3 milliamperes is needed to make a spark visible to the human eye in normal lighting conditions. However, this can vary depending on factors such as the distance from the spark and ambient light levels.

Most drinking straws are made of plastic, which is generally not electrically conductive. However, paper straws may contain additives or coatings that could potentially make them conductive. It is always a good idea to exercise caution when using any materials near electrical sources.

Charge would flow from the charged electroscope to the initially uncharged one,

until the charges are equal on both. At that point, the potential on both ends of

the wire would be equal, there would be no voltage across the wire, and no more

current would flow. Both electroscopes would then be charged, with charge of

the same sign, and with half as much charge as the initially-charged one had.

static electricity there is no flow of electrons and it is a result of imbalance of positive and negative charges only.while dynamic electricity , the flow of electrons can be either in a single direction(direct current),or it can be changing directions repeteadly (alternating current)..!

Static electricity is produced when two materials rub against each other, causing a transfer of electrons. When you run a comb through your hair, it creates friction which can result in the transfer of electrons, leading to a build-up of static charge. This static charge causes individual strands of hair to be attracted to the comb, creating the effect of the hair sticking to the comb.

Static electricity is caused by the transfer of electrons between objects. When two objects rub against each other, one object may lose electrons and become positively charged, while the other gains electrons and becomes negatively charged. The resulting imbalance of positive and negative charges creates a difference in electrical potential, leading to static electricity.

The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.

Static electricity can be used in various real-life applications, such as removing dust and debris with a static electricity-powered dusting cloth, printing using electrophotography (e.g., laser printers), or sticking a balloon to a wall through static cling. Providing charge to objects via static electricity can also help with processes like electrostatic painting or air filtration.

The balloon will have static electricity after being rubbed on the woolen cloth. This results from the transfer of electrons between the balloon and the cloth, causing the balloon to become negatively charged.

No, the amount of work per unit charge required to transfer electric charge in an electrostatic field does not depend on the amount of charge transferred. This quantity is known as the electric potential difference and is a characteristic of the electric field itself, regardless of the charge being moved.

Static electricity in your body is often caused by a build-up of electrical charge, usually from friction between surfaces like your clothes and skin. When you touch a conductive object, like metal, the charge is discharged and you feel a static shock. Dry environments, certain materials, and rapid movements can all contribute to the buildup of static electricity.

Uncharged means that there are an equal number of protons and electrons. When the negative rod is held near the neutral metal ball, the electrons from the metal ball repel from the electrons on the rod bringing the protons closer to the rod causing the metal ball to be attracted to the negatively charged rod. It's called charging by induction.

When the balloon is rubbed with wool, it gains a negative charge while the tissue paper remains positively charged. Opposite charges attract, causing the tissue paper to stick to the balloon. This is due to the transfer of electrons from the wool to the balloon, creating an electric charge imbalance between the two objects.
