Two charges -q and +q are located at points (0,0,-a) and (0,0,a) respectively.
(c ) How much work is done in moving a small test charge from the point (5, 0, 0) to (-7, 0, 0) along the x-axis?

Text Solution

Verified by Experts

The work done is zero because the potential along the x-axis is zero.
The work done is always zero between these two points because work done not depend on the path taken, it only depends on the position of the end points.
