Imagine a short doiploe at the center of a spherical surface. If the magnitude of the electric field at a certain point on the surface of he sphere is `10NC^(_1)` then which of the following cannot be the magnitude of the electric field anywhere on the surface of the sphere?

A

`4NC^(-1)`

B

`8NC^(-1)`

C

`16NC^(-1)`

D

`32NC^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
(i) Let electric field at '1' be `10NC^(-1)`, then at '2' it is `5NC^(-1)` and at any other point on surface of sphere electric field will be form `5NC^(-1)` to `10NC^(_1)`.
(ii) Let electric field at '2' is `10NC^(_1)`, then at '1' it is `20NC^(_1)` and at any other point on surface of sphere electric field will be from `10NC^(_1)` to `20NC^(_1)`
