Q1) An electric charge is placed near an object whose net charge is zero.

(a)If the object is made of metal, does the charge exert a force on the object? If so, is it

attractive or repulsive?

(b)If the object is made of plastic, does the charge exert a force on the object? If so, is it attractive or repulsive?

Q2) Two identical charged particles of mass m=1.6 kg and electric charge Q=-4.7x10^-6 C are placed on an frictionless 25° incline. One of them falls down to the bottom and stops against the wall. The other stays at rest in the middle of the incline as shown in Figure. Find is the distance between the particles.

Q3) A parallel plate capacitor of area 0.0141 m2 carries electric charge as shown in Figure. A 7.05 10-3-kg plastic ball with a charge -0.156 µC is suspended from a ceiling with an insulating thread such that the ball stays between the plates of the capacitor. The ball and thread are rest with angle ?=30.5°.

(a) What is the magnitude of the electric field between the plates?

(b) What is the net charge on the left plate? Detailed responses, please
