Positive and negative point charges of equal magnitude are kept at (0,0,a/2) and (0,0,−a/2) respectively. The work done by the electric field when another positive point charge is moved from (−a,0,0) to (0,a,0) is −a/2) respectively. The work done by the electric field when another positive point charge is moved from (−a 0) is 0) [...]

Two charges q1 and q2 are placed 30cm apart, as shown in the figure. A third charge q3 is moved along the arc of a circle of radius 40cm from C to D. The change in the potential energy of the system is q3/4πε0 k., where k is as shown in the figure. A third [...]
