1.	a. A circle is drawn with center as a charge +q. What is the work done in moving a charge +q from B to C along the circumferebce of the circle ? B In the above question, if the charge +q is first taken from B to A and then from A to C, on which path is the magnitude of work greater ? .
Answer» a. Points B and C lie on equipotential surface. So work done is zero. b. `V_B - V_A = V_C - V_A`, so magnitude of change in potential is same, hence, magnitude of work done will be the same.
