A point charge Q is moved along a circular path around another fixed point charge The work done is zero 
  • a)
    only if Q returns to it's starting position
  • b)
    in all cases
  • c)
    only if the two charges have the same magnitude and opposite signs
  • d)
    only if the two charges have the same magnitude
Correct answer is option 'B'. Can you explain this answer?

A point charge Q is moved along a circular path around another fixed p...
Explanation:
When a point charge is moved along a circular path around another fixed point charge, work is done on the charge by the electric field created by the fixed charge. The work done is given by the equation:

W = ∆U = Uf - Ui

Where W is the work done, ∆U is the change in potential energy, Uf is the final potential energy, and Ui is the initial potential energy.

When a point charge is moved along a circular path around another fixed point charge, the final and initial positions of the charge are the same. Therefore, the change in potential energy is zero, and the work done is also zero.

Hence, the work done is zero in all cases when a point charge is moved along a circular path around another fixed point charge.
