Question

Two isolated metallic solid spheres of radii R and 2R are charged such that both of these have same charge density s. The spheres are located far away from each other, and connected by a thin conducting wire. Then the new charge density on the bigger sphere is. 

Options

A.
B.
C.
D.

Solution


Charge on bigger sphere Q2′ = .C2
Q2′ = × 4π ∈0 × 2R =
Surface charge density on bigger sphere σ′ =
