A charge (-1C) moves in a uniform electric field E=2v/m, AC=2m, AB= m, angleCAB=135°. AC is parallel to electric field, the charger moves from A to B, B to C, and from C back to A. Find the potential energy change for the charger when it moves from point A to B, B to C and from C back to A, then find the total potential energy change for the entire motion. (20 points)

Draw the electric field line for two same positive chargers, one positive and one negative (same absolute value). (10 points)
Draw the electric field line for a sphere conductor placed between a positive charger and a negative charge (same absolute value), and the equipotential lines. (20 points)
