On a 1 whole pad paper:
5) Metal sphere A has 4 units of negative charge and metal sphere B has 2 units of positive charge. The 2 spheres are brought into contact. What is the final charge of each sphere? Explain.
6)
a. Metal sphere A is initially neutral. A positively charged rod is brought near, but not touching. Is A now positive, negative or neutral? Explain and illustrate.
b. Metal spheres A and B are initially neutral and are touching. A positively charged rod is brought near A, but not touching. Is A now positive, negative or neutral? Explain and illustrate.
c. Metal sphere is initially neutral. It is connected by a metal wire to the ground. A positively charged object is brought near the sphere, but not touching. Is A now positive, negative or neutral? Explain and illustrate.
7) If 16 million electrons are removed from a neutral sphere, what is the charge on the sphere in coulombs?
Please tell me if something is wrong in the questions :)
