Three conducting concentric spherical shells A, B and C having radii a, 2a and 3a respectively are placed as shown. Initially A and C carry some positive charge whereas shell B is uncharged. Now switch S is closed. The potential difference (VA – VB) between shell A and B will-
A
Increase
B
Decrease
C
Remain unchanged
D
Increase or decrease depending upon actual amount of charges on A and C.
Answer
Remain unchanged
Explanation
Solution
After switching on electric field between A & B remain unchanged
\ potential difference between A & B remain unchanged.
