Question 100

A spherical metal dome of a Van de Graaff generator has a radius RRR. When charged, the electric potential at a distance of 3R3R3R from the centre of the dome is V0V_0V0​.

What is the magnitude of the electric field strength EEE at the surface of the dome?

A

V03R\frac{V_0}{3R}3RV0​​

B

V0R\frac{V_0}{R}RV0​​

C

3V0R\frac{3V_0}{R}R3V0​​

D

9V0R\frac{9V_0}{R}R9V0​​
