Question

Generalised expression of potential energy of system of N point charges

Answer 1

Explanation:

V = k × [q/r]

V = electric potential energy, q = point charge, r = distance between any point around the charge to the point charge, k = Coulomb constant; k = 9.0 × 109 N.

General Formula: Voltage = Energy / charge

Denoted by: V, ∆V, U, ∆U

SI Unit: Volt

Dimension: ML2T-3A-1.
