Electric Charges and Forces Principles
Each corner of a right angled triangle is occupied by identical point charges "A", "B", and "C" respectively. Draw a sketch of this arrangement. "A" exerts force F on "B". An equal force F is exerted by "C" on "B" (deltaABC=90 degrees). Determine an expre
Why do the two leaves of a neutral electroscope go apart when a positive rod is brought near the cap (but not touching it)?
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.
Two electric objects experience a repulsive force. What happens to that force if the distance between the objects is doubled?
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.
Two small charges +4.0 x 10-5 C and -1.8 x 10-5 C, are placed 24 cm apart. What is the force on the third small charge, of magnitude -2.5 x 10-6 C, if it is placed on the line joining the other two and
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?
Two pith balls each hang from a thread and are suspended from the same hook. If each pith ball is charged -6.4 X 10^-5 C and they are separated by a distance of 0.56 cm, what is the force between them?
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
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?
