Question

There are three co-centric conducting spherical shells A, B and C of radii a, b and c respectively (c > b > a) and they are charged with charge q₁, q₂ and q₃ respectively. The potentials of the spheres A, B and C respectively, are:

Accepted Answer

(B) 1/(4πε₀)(q₁/a + q₂/b + q₃/c), 1/(4πε₀)((q₁ + q₂)/b + q₃/c), 1/(4πε₀)((q₁ + q₂ + q₃)/c)

Answer

(A) 1/(4πε₀)((q₁ + q₂ + q₃)/a), 1/(4πε₀)((q₁ + q₂ + q₃)/b), 1/(4πε₀)((q₁ + q₂ + q₃)/c)

Answer

(C) 1/(4πε₀)(q₁/a + q₂/b + q₃/c), 1/(4πε₀)((q₁ + q₂ + q₃)/b), 1/(4πε₀)((q₁ + q₂ + q₃)/c)

Answer

(D) 1/(4πε₀)((q₁ + q₂ + q₃)/a), 1/(4πε₀)((q₁ + q₂)/b + q₃/c), 1/(4πε₀)(q₁/a + q₂/b + q₃/c)
