Charge on the outer sphere is and the inner sphere is grounded. The charge on the inner sphere is , for . Then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Since the inner sphere is grounded, potential of the shell must be zero due to the charges on outer sphere and inner sphere. ⇒kq'r1+kqr2=0 ⇒kq'r1=-kqr2 ⇒q'=-r1r2q
