Conducting sphere of radius `R_(1)` is covered by concentric sphere of radius `R_(2)`. Capacity of this combination is proportional to

A

`(R_2-R_1)/(R_1R_2)`

B

`(R_2+R_1)/(R_1R_2)`

C

`(R_1R_2)/(R_2+R_1)`

D

`(R_1R_2)/(R_2-R_1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`C=4piepsilon_0((R_1R_2)/(R_2-R_1))implies C prop (R_1-R_2)/(R_2-R_1)`
