Two metal spheres `A` and `B` have their capacities in the ratio `3:4` they are put in contact with each other and an amount of charge `7xx10^(-6)C` is given to the combination .Next the two spheres are separated and kept wide the apart so that one has no electrical influence on the other.The potential due to the smaller sphere at a distance of `50m` from it is

A

540V

B

270V

C

1180V

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
`q_(1) = ((r_(1))/(r_(1) + r_(2))) q, V_(1) = (1)/(4pi epsi_(0)) (q_(1))/(r )`
