Explain, giving each step, how a positively charged insulatingrod can be used to give a metal sphere (a) a negative charge and (b) a positive charge. (c)Can the same rod be used to simultaneously give one sphere a positive charge and anothersphere a negative charge without the rod having to be recharged?

Explanation / Answer
Negatively charged forces electronmovement to side of the second sphere. Once touched by the ground, the electronsleave the sphere, there is an overall positive charge left onthe sphere.
