The figure shows a −Q charge and +Q charge, and two paths (the dashed lines) to get from points 1 to 2. If a positive charge +q0 moves from 1 to 2, on which path will more work be done on the +q0 charge? Equal amounts of work are done on each path More work is done on the straight path. More work is done on the curved path. What is the sign of the change in electric potential energy of the 3-charge system (involving charges +Q, −Q, and +q0) as the +q0 moves from 1 to 2 along the straigh path? The change in electric potential energy is negative. The change in electric potential energy is zero. The change in electric potential energy is positive.
