A ring of radius `0.5 m` carries a total charge of `1.0xx 10^(-10)C` distributed non uniformly on its circum Ference, producting an electric field `vecE`. The value of `int_(r = oo)^(r = 0) -vecE.vecd r (r = 0` being the centre of the ring)is

A

`+1.8 V`

B

`-6 V`

C

`-1.8 V`

D

`+6 V`

Text Solution

Verified by Experts

The correct Answer is:
A
`V = (9 xx 10^(9) xx 1xx 10^(-10))/(0.5) "volt" = 1.8 "volt"`.
