In a region of constant potential

A

the electric field is uniform

B

the electric field is zero

C

there can be no charge inside the region.

D

the electric field shall necessarily change if a charge is placed outside the region.

Text Solution

Verified by Experts

The correct Answer is:
B, C
E and V are related to ,
`E = -(dV)/(dr)`
E =0 then V = constant
Here `(dV)/(dr)` =0 hence E =0 , so according to `E = (kq)/(r^(2)), q =0`
`:. ` True options are (B) and ( C ).
