Question

The magnitude of the electric field on the surface of a sphere of radius r having a uniform surface charge density σ is
  1. σ/ϵ0
  2. σ/2ϵ0
  3. σ/ϵ0r
  4. σ/2ϵ0r

A
σ/ϵ0
B
σ/2ϵ0
C
σ/2ϵ0r
D
σ/ϵ0r
Solution
Verified by Toppr

The magnitude of the electric field on the surface of radius =r
Charge density =6
Then, E=6ϵ0
The electric field is independent of the surface radius.
