Question

A non-conducting ring of radius 0.5 m carries a total charge of 1.11 × 10-10 C disturbed non-uniformaly on its circumference producing an electric field E everywhere in space.
The value of integral (l = 0 being centre of the ring) in volts is

Options

A.+ 2
B.- 1
C.- 2
D.zero

Solution

= V(centre) - V(infinity)
but V (infinity) = 0
∴    corresponding to potential at centre of ring.
and V(centre) =
        2 volt
