Question

1. (18.3.25) Point charges of 5.00 μC and-3.00 are placed 0.250 m apart. (a) Where can a third charge be placed so that the net force on it is zero? (b) What if both charges are positive? 2. (18.8.51) (a) What is the electric field 5.00 m from the center of the terminal of a Van de Graaf with a 3.00 mC charge? Note that the field is equivalent to that of a point charge at the center of the terminal. (b) At this distance, what force does the field exert on a 2.00 Graaf's belt? charge on the Van de
