Two concentric spherical surfaces A and B are equipotential surfaces for a positive charge +q placed at the centre. First we place another positive charge +Q between A and B, as shown in Figure 1. • a) In which direction will the new charge (+Q) move (radially outwards or inwards)? Justify your answer. • b) How will the electrostatic potential energy of +Q change? Justify your answer.  • c) Next, consider that the +Q is instead placed at point B. What would the work then be done to move it from point B to point C? Justify your answ
