A nonconducting ring of radius \( \mathrm{R} \) has uniformly distributed positive charge Q. A small part of the ring, of length \( \mathrm{d} \), is removed \( (\mathrm{d}\mathrm{R}) \). The electric field at the centre of the ring will now be
\( P \)
(A) directed towards the gap, inversely proportional to \( \mathrm{R}^{3} \).
(B) directed towards the gap, inversely proportional to \( \mathrm{R}^{2} \).
W
(C) directed away from the gap, inversely proportional to \( \mathrm{R}^{3} \).
(D) directed away from the gap, inversely proportional to \( \mathrm{R}^{2} \).
