Electrostatics Question 460

Question: A thin spherical conducting shell of radius R has a charge q. Another charge Q is placed at the centre of the shell. The electrostatic potential at a point p a distance R2 from the centre of the shell is [AIEEE 2003]

Options:

A) (q+Q)4πε02R

B) 2Q4πε0R

C) 2Q4πε0R2q4πε0R

D) 2Q4πε0R+q4πε0R

Show Answer

Answer:

Correct Answer: D

Solution:

Electric potential at P V=k.QR/2+k.qR

=2Q4πε0R+q4πε0R
