Electrostatics

No, two different equipotential lines cannot cross each other. Equipotential lines are points in a space at which the electric potential has the same value. If two equipotential lines were to cross, it would mean that the electric potential at that point has two different values, which is not possible according to the definition of equipotential lines.

Charles-Augustin de Coulomb discovered the relationship between electric charges, their separation, and the force between them. This relationship is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Here electrons get migrated from one region to the other. Here no contiuous flow of electrons. As electrons get migrated to one region, then negative potential created would oppose further migration of electrons and hence a negativ potential is created. This is what we call CHARGED. A capacitor is a device to store electric charges by following the phenomenon of electrostatic induction.

It's very fortunate that the answer doesn't depend on the amount of the original

charge, because I'm really having a lot of trouble reading the above amount.

The answer only depends on the changes, and following the changes you've described,

the force of repulsion between the spheres is unchanged. If the initial force is marked

there in the book you copied the question from, then the final force is exactly the same number.

Technically, an antenna only works with good safety and efficiency at one single

frequency, or over a narrow band of contiguous frequencies. If you need to operate

over a wide band of frequencies, or in several different bands, with high efficiency,

you'd nominally need several separate antennas. Since that would be a real pain,

several trustworthy, loyal, helpful, friendly, courteous, kind, obedient, cheerful, thrifty,

brave, clean, clever, competent, dedicated, and innovative engineers ... most of them

being obviously ham radio operators ... figured out how to build antennas that would

work well over a wide range of frequencies or on widely separated bands. One such

category of antennas is known as the multi-band dipoles, for the basic design that

they resemble. The 'dipole' antenna is generically one with equal lengths of radiator

extending in two opposite directions from the end of the "feeder" (transmission line),

and it is this design with which tricks may be played in order to derive many wideband

and multiband designs.

Rubbing two different materials against each other can transfer electrons between the materials, causing one to become positively charged and the other negatively charged. This separation of charges creates static electricity.

1. It is, what thunder and lightening is.
2. It makes your jumper crackle, when you pull it over your head.
3. It makes balloons stick to the ceiling, after you have charged them up by rubbing on fabric or hair.
4. It makes your clothes stick together, when you get them out of the tumble dryer.
5. It gives you a shock, when you insert the key to a hotel room door, after walking on synthetic carpets.

Static electricity is the buildup of electric charge on an object's surface, which can cause sparks or shocks when discharged. Current electricity, on the other hand, involves the flow of electric charge through a conductor, typically in a closed loop circuit. Both types of electricity involve the movement of electrons, but static electricity remains stationary while current electricity flows in a continuous loop.

A positively charged object placed within a positive electric field will experience a force pushing it in the direction of the field. This force will cause the object to accelerate in the direction of the field lines.

The question is about comparing two different quantities. Static electricity is a physical phenomenon (for example, heat). It is about the accumulation of electrons or the lack of electrons on insulating surfaces. Magnesium is a metal, a material, that is a conductor and burns brightly when lit. Other than that Magnesium cannot accumulate electrons at the surface to cause static electricity, I don't see any relation.

In common practice, the principle reservoir for electric charge is a battery. Fuel cells, which are like batteries except with external reactant sources, are becoming more widely used as electric reservoirs. In pure circuit design, the capacitor is used as the charge reservoir.

Slow running water in proximity to an electrically charged object (such as an inflated baloon with its surface filled with static electricity) will bend towards towards the object. The reason for this is that most water (if it is not de-ionized) contains positively and negatively charged ions. The ions with the same charge as the surface of the charged object will be pushed back into the faucet, leading to a buildup of ions with the opposite charge. Since opposite charges attract, the ions remaining in the water will be pulled towards the charged object, and the water will be pulled with the ions.

-- Connect a source of known, small voltage across the ends of the unknown resistance.

-- Measure the resulting current through the unknown resistance.

-- Divide (small known voltage)/(measured current). The quotient is the formerly unknown resistance.

Lightning is produced by the buildup and discharge of static electricity in the atmosphere, typically caused by the separation of positive and negative charges within a cloud or between a cloud and the ground. So, it is produced by static charge rather than being static charge itself.

Yes, a capacitor stores energy by storing electric charge in an electrostatic field between two conductive plates. When a voltage is applied across the capacitor, it stores energy in the form of electric potential energy.

Examples of things that produce heat and light include the sun, a burning candle, a light bulb, and a campfire. These sources emit energy in the form of both heat and light through various processes such as combustion or nuclear fusion.

By bringing a charged ball into contact with two others, the charges will equalize across all three balls. Electrons will stream off the two previously uncharged balls (assuming they were), and will reduce the positive charge on the first ball. This will leave the other balls positively charged. All three balls will be charged to some extent, and, though there will be differences on the charges on the balls, there should be no difference in voltage between the balls. Bringing them back into contact will not (should not) result in any more charge movement.

Yes, ironing can help reduce static in fabrics by smoothing out wrinkles and releasing built-up static electricity. Using a steam iron on a low setting can also add moisture to the fabric, further reducing static cling.

The gravitational force (Fg) between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. The magnetic force (Fm) between two moving charged particles is a function of their velocities and the magnetic field. The electrostatic force (Fe) between two charged particles is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Static electricity is considered a charge because it involves the accumulation of excess electrons on an object's surface, leading to an imbalance of positive and negative charges. This charge does not flow continuously like a current, but rather remains in place until discharged through an electrical conductor.

Static electricity is also known as electrostatic charge or static charge.
