Question

Two charged particles, having equal charges of 2.0 x 10^-5C each, are brought from infinity to within a separation of 10 cm. Find the increase in the electric potential energy during the process.

Answer 1

q₁ = q₂ = 2 × 10^–5 C
Each are brought from infinity to 10 cm a part d = 10 × 10^–2 m
So work done = negative of work done. (Potential E)
