Assertion - Two concentric spherical shell of different radius are at potential VA and VB. If outer shell is earthed then potential difference will not be changed.
Reason- Potential difference between the surfaces of two concentric spherical shells does not depends on the charge on the outer shell.
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is not the correct explanation of A.
C) A is true but R is false.
D) A is false and R is also false.
