Electrostatics Question 362

Question: At a certain distance from a point charge the electric field is $ 500V/m $ and the potential is $ 3000V $ . What is this distance [MP PMT 1995; Pb. PMT 2001; AFMC 2001]

Options:

A) $ 6m $

B) $ 12m $

C) $ 36m $

D) $ 144m $

Show Answer

Answer:

Correct Answer: A

Solution:

$ V=E\times r $

therefore $ r=\frac{V}{E}=\frac{3000}{500}=6m $
