Let's Begin:


This is a fairly simple one:

Given is a uniform line charge of shape as shown. Find the value/(s) of the angle A such that the electrostatic field at the center (of the loop/arc shown ) is zero.

    i was just trying to solve myself...i think that if you know the direction of field due to a semi infinite line, the answer follows...

    accha...there was a bit more to it..how many values of A exist b/w 0 and 2n(pi)?

    2n(pi) means giving more than 1 circluar arc imposed on the other or something like that?
    Should be just 1 I suppose
