Q -> A charged particle of charge is moved around a charge +q along a circular path of radius r from A and B. The workdone is ..
- zero.
solution : The charged particle is moving on the equipotential surface. I mean, potential at point A = potential at point B.
so potential difference = 0
we know, workdone due to charge is product of charge and potential difference
i.e., W = × ∆V
= × 0
= 0
Therefore workdone is zero. so option (4) is correct choice.
