Question

A non-conducting ring of radius 0.5m carries a total charge of $1.11 \times 10^{- 10} C$ distributed non-uniformly on its circumference producing an electric field $\to E$ every where in space. The value of the line integral $\int_{l - 0}^{l - \infty} - \to E . d \to l$ ( $l - 0$ being centre of the ring) in volts is
