Answer» EXPLANATION:σ(4πr2+4πR2)=Q ∴σ=Q4π(r2+R2) Potential at CENTRE = potential DUE to A+potential due to B =σrε0+σRε0 =σε0(r+R) (Q4πε0)(r+Rr2+R2)

A charge 'q' is distributed over two concentric hollow coducting sphere of radii r and R(>r) such that their surfacharge densitites are equal. The potential at their commcentre is

Answer»

EXPLANATION:σ(4πr2+4πR2)=Q

∴σ=Q4π(r2+R2)

Potential at CENTRE

= potential DUE to A+potential due to B

=σrε0+σRε0

=σε0(r+R)

(Q4πε0)(r+Rr2+R2)
