Q. A small remote-control car with a mass of 1.59 kg moves at a constant speed of v = 12.0 m/s in a vertical circle inside a hollow metal cylinder that has a radius of 5.00 m.

What is the magnitude of the normal force exerted on the car by the walls of the cylinder at point A (at the bottom of the vertical circle)?

Q.The two charges are separated by a distance d = 1.50 cm, and Q = +2.40 nC.

(a) Find the electric potential at A.

(b) Find the electric potential at B.
