The electric field at the surface of a charged spherical conductor is 10 KV/m. The electric field at a distance equal to the diameter from its centre will be –

A

2.5 V/m

B

2.5 K V/m

C

5.0 K V/m

D

5.0 V/m

Answer

5.0 K V/m

Explanation

Solution

Enet = E1 + E2

= σ2ε0\frac { \sigma } { 2 \varepsilon _ { 0 } }+ σ2ε0\frac { \sigma } { 2 \varepsilon _ { 0 } } = σε0\frac { \sigma } { \varepsilon _ { 0 } }
