A non-conducting ring of radius `0.5 m` carries a total charge of `1.11xx10^(-10)`C distributed non-uniformly on its circumference producing an electric field E everywhere is space. The value of the integral `int_(l=oo)^(l=0)-E.dI (l=0` being centre of the ring) in volt is

A

`+2`

B

`-1`

C

`-2`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(0) = K (q)/(R ), V_(oo) = 0, underset(t= oo)overset(t = 0)int - vec(E ).vec(dl) = V_(o) - V_(oo)`
