Electrostatics
Electrostatics is the branch of physics that deals with the study of charges at rest. A common electrostatic phenomena is plastic wrap sticking to your hand and itself when removed from the box. Everything to do with electrostatics goes in this category.

Uh, assuming by "spherical body" you mean "spherical shell of insignificant thickness" then it would just be 4*pi*(R^2)*sigma
Why is a static discharge if you touch a metal doorknob after walking on a wool carpet?
energy form rubbing your feet on the carpet is acumulated "in" you, and the doorknob acts a ground. Once you touch the doorknob, the energy exits. It makes more sense if you think that you are the positive end of a circuit, and the energy goes through the circuit, and the spak can be thought of as an LED.
What can be attracted by a positively charged object?
A negatively charged object. Also, a neutral object, through an induced separation of charges.
Is the ability to smell static electricity normal?
Other websites say it is possible through o-zone but i can smell it's current
Who discovered electricity not static electricity?
Benjamin Franklin is credited with discovering electricity in the form of lightning, not static electricity. In 1752, he famously conducted his kite experiment during a thunderstorm to demonstrate the electrical nature of lightning.
What is the difference between positive crystals and negative crystals?
Normally crystals do not have electrical charge.
A few types of crystals (e.g. quartz) will develop an electrical charge across them when placed under mechanical stress. This property is called piezoelectricity. But the positive and negative charges are on opposite sides of one crystal, not on two different crystals.
Perhaps you were actually thinking of something that has nothing to do with science or electricity when you asked this question.
How can static electricity generate an electrical force to make your hair stand on end?
Static Electricity generator an electrical force can make your hair stand on end that happens because, your hair has picked up extra electrons. This causes your hair to repel against each other(Like charges repel remember!). Because you hair is so tightly packed, the furthest any hair can get from another hair is to stand straight up.
What creates static charge without contact?
Static charge can be created without contact through the process of induction. When a charged object is brought near a neutral object, the charges within the neutral object are rearranged, creating a separation of charges and resulting in a static charge on the object without direct contact.
The negatively charged rod induces a positive charge at the side of the can closest to it, attracting negative charges to the opposite side. When you touch the opposite side with your finger, electrons flow from your finger to neutralize the positive charge. If you remove your finger before removing the rod, the positive charge induced by the rod will redistribute, making the can net-neutral again.
Why does static charge only build up on the surfaces of materials?
Static charge builds up on the surfaces of materials because the electrons move more easily in materials compared to the protons. When two materials come into contact, electrons can transfer from one material to the other, leading to an imbalance of charges on the surface of the materials. This imbalance creates a static charge on the surface.
Static is used in programming to declare variables or methods that belong to a class rather than an instance. It is also used for static web pages, which are fixed in content and layout. Additionally, static electricity is commonly used in materials handling and manufacturing processes.
How a conductor can build up a static charge?
A conductor can build up a static charge by gaining or losing electrons through friction with another material. This excess or deficit of electrons creates an imbalance in charge, leading to a build-up of static electricity on the surface of the conductor.
If you rub a coin briskly between your fingers it will not seem to become charged by friction. Why?
Coins are made of metal which is a good conductor of electricity. When you rub a coin briskly between your fingers, any static charge that builds up on the coin is quickly dissipated due to the coin's high conductivity, preventing it from becoming noticeably charged.
Is rubbing a ballon in your hair a static charge?
Yes, rubbing a balloon against your hair can create a static charge. This is because the friction between the balloon and your hair causes the transfer of electrons, leading to a buildup of static electricity on the balloon.
What is the strength of cobalt electrostatic force?
The strength of the cobalt electrostatic force depends on the charge of the cobalt ions involved. Cobalt can exist in different oxidation states, so the strength of the electrostatic force can vary accordingly. Generally, cobalt ions with higher charges will exhibit stronger electrostatic forces.
Not necessarily. If a body has the same charge as a glass rod (negative), it means the body is negatively charged. The charge is determined by the excess or deficit of electrons on the body.
What is electrostatic spectrum?
I don't think there is such a thing. You may be confusing this with "electromagnetic spectrum".
Yes, that is correct. When fuel containers are not properly grounded and bonded, static electricity can build up and discharge, potentially igniting flammable vapors and leading to fires or explosions. Implementing proper grounding and bonding practices helps to safely dissipate static charges and prevent this risk.
Circle the letters of the factors that the strength of an electric field depends on.?
The strength of an electric field depends on the charge that causes it, and on the distance from the charge.
What do electric charges that are different do?
Electric charges that are different attract each other. This is based on the principle that opposite charges attract. When different charges are brought close together, they will tend to move towards each other.
What will happen if you bring two objects that have static electricity close to one another?
The two objects will either attract or repel each other, depending on the charge of the static electricity. Like charges (positive-positive or negative-negative) will repel each other, while opposite charges (positive-negative) will attract each other. This is due to the forces of attraction and repulsion between electrically charged particles.
A cloth dryer generates static electricity because different fabrics rubbing against each other create friction. This friction transfers electrons between the clothing, causing them to become positively or negatively charged. When the clothes rub against the dryer drum, this can lead to a buildup of static electricity.
How can you prevent a static Spark while filling your boat with fuel?
A grounding wire between your boat and the dock can discharge any static sparks before you begin to fuel up.
