3. An electric field is established between two parallel plates as shown in figure 3. The plates are 50 cm apart and a potential difference of 1000 V is applied between them. A 30cm B 50cm 1000V Figure 3 A point charge of +1.0 µC is at point A and then moves first to point B, then to point C and finally back to point A. Calculate: a) the force experienced by the charge at A, b) the force experienced by the charge at B, c) the work done in moving the charge from A to B (distance 30 cm), d) the work done involved in moving the charge from C to A (clearly explain your answer to this part).
