Ten electrons are equally spaced and fixed around a circle of radius `R`. Relative to `V = 0` at infinity, the electrostatic potential `V` and the electric field `E` at the centre `C` are

A

`V ne 0 and vecE ne 0`

B

`V ne 0 and vecE = 0`

C

`V = 0 and vecE = 0`

D

`V = 0 and vecE ne 0`

Text Solution

Verified by Experts

The correct Answer is:
B
At center E = 0 (due to symmetry)
`V ne 0`
