A uniformly charged hemisphere of radius b and charge density ρ has a hemispherical cavity of radius a a = b 2 cut from its centre. If the potential at the centre of the cavity is n ρ b 2 16 ∈ 0 then n = ?

Question

A uniformly charged hemisphere of radius b and charge density ρ has a hemispherical cavity of radius a a = b 2 cut from its centre. If the potential at the centre of the cavity is n ρ b 2 16 ∈ 0 then n = ?, 3, 4, 5, 6

V = ∫ a b K 2 π x 2 d x ρ x V = 2 π k ρ b 2 - a 2 2 = π ρ k b 2 - a 2 b = 2 a v = 3 π k ρ b 2
