A charge of 1.6 x 10-10C is placed in a uniform electric field of intensity 2.0 x 105NC-1. What is the magnitude of the electric force exerted on the charge?
Calculate the electric potential at a distance of 20.0cm from a point charge of 0.015C placed in air of permittivity (Take \(\frac{1}{4πεo}\) as 9.0 x 10\(^9\) Nm\(^2\)C\(^2\))
