Electric Charges & Fields: Gauss's Law
Which of the following describes the primary difference between charging by contact and charging by induction?
Two identical metal spheres, A and B, are initially neutral. Sphere A is given a charge of +4Q. Sphere A is then brought into contact with sphere B and separated. What is the final charge on each sphere?
Which of the following statements is true regarding electric charge?
Which method of charging involves the transfer of electrons through rubbing two neutral objects together?
A charged rod is brought near a neutral piece of paper. The paper is attracted to the rod. Which of the following explains this phenomenon?
An object has a net charge of C. How many excess electrons does it have?
A positively charged rod is used to charge a neutral metal sphere by contact. What will be the charge of the metal sphere after the rod is removed?

What happens when a charged metal sphere is connected to the ground?
A negatively charged metal sphere is grounded. In which direction do the electrons flow?
A negatively charged rod is brought near, but not touching, a neutral conducting sphere. The sphere is then grounded while the rod is nearby. What is the final charge on the sphere after the ground connection is removed and then the rod is removed?
