Charge q₂ is at the centre of a circular path with radius r. Work done in carrying charge q₁, once around this equipotential path, would be (a) (1)/(4πε₀) × (q₁q₂)/(r²) (b) (1)/(4πε₀) × (q₁q₂)/(r) (c) zero (d) infinite

Answer: (c). The circle is an equipotential: start and end potentials are equal. W = q₁ Δ V = 0 So the answer is (c) zero.
