Two conducting spheres of radii 5 cm and...

Two conducting spheres of radii `5 cm` and `10 cm` are given a charge of `15mu F` each. After the two spheres are joined by a conducting wire, the charge on the smaller sphere is

A

`20muC`

B

`5muC`

C

`10muC`

D

`15muC`

Text Solution

Verified by Experts

The correct Answer is:
C
`V = (Q_(1) + Q_(2))/(4pi in_(0) (r_(1) + r_(2))) and Q_(1)^(1) = 4pi in_(0) r_(1)V`
