The electrostatic force between two point charges is 6.0x10^-5 N. IF the distance between the, is halved, the charge of one of the points doubles and the charge of the other point triples. What will be the force between them?
Three identical conducting spheres are on insulated stands and are not touching one another initially. Sphere A has a charge of +10 µC, Sphere B has a charge of -6 µC, and Sphere C has a charge of -4 µC. Sphere A contacts Sphere B, and they are separated.
There are four charged objects: A, B, C, and D. Object A is charged positively. Object A is attracted to Object B. Object B is repelled from Object C. Object C is attracted to Object D. What are the charges on Objects B, C, and D?
Two electric objects experience a repulsive force. What happens to that force if the distance between the objects is doubled?
A pith ball is a tiny piece of Styrofoam that is covered with a conductive paint. One pith ball initially has a charge of +6.4 X 10^-5 C, and it touches an identical, neutral pith ball. After the pith balls are separated, what is the charge on the pith ba
Two equally charged pith balls are 2.0 cm apart and repel each other with6.5 X 10^-5 N of force. Calculate the charge on each pith ball.
A negative object is brought near the left side of a conducting sphere but does not touch it. Meanwhile, a person briefly touches the right-hand side of the sphere. What happens to the sphere in this process?
Calculate the ratio of the electric force to the gravitational force between an electron and a proton.
A 2 C charge and a -4 C charge attract each other with 100 N of force when placed a certain distance apart. With how much force will a 4 C and a -4 C charge attract each other when placed the same distance apart?
Paper is considered an insulator. How does a positively charged piece of tape pick up a neutral paper bit?
