- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
In the above case, the formula of spherical capacitor consists of two concentric spherical conductors of radius, r1 and r2 is, C=4πε0r1r2r1-r2 Here r1=R and r2=2R, now put the values in the above formula, C=4πε0R2R2R-R=8πε0R
