Problem

A non-conducting ring of radius

0.5\,\text{m}

carries a total charge of

1.11\times10^{-10}\,\text{C}

distributed non-uniformly on its circumference, producing an electric field

\mathbf{E}

everywhere in space. The value of the integral

\int_{l=\infty}^{l=0}-\mathbf{E}\cdot d\mathbf{l}

, where

l=0

is the centre of the ring, is (a)

+2

(b)

-1

(c)

-2

(d)
