Two identical thin rings, each of radius...

Two identical thin rings, each of radius R, are coaxially placed at a distance R. If `Q_(1) and Q_(2)` are respectively, the charges uniformly spread on the two rings, find the work done in moving a charge q from centre of ring having charge `Q_(1)` to the other ring.

A

Zero

B

`(q(Q_(1)-Q_(2))(sqrt(2)-1))/(sqrt(2).4piepsilon_(0)R)`

C

`(2sqrt(2)(Q_(1)+Q_(2)))/(4 pi epsilon_(0)R)`

D

`(q(Q_(1)+Q_(2))(sqrt(2)+1))/(sqrt(2).4 pi epsilon_(0)R)`
