Problem

An α\alpha-particle (charge = +2e+2e, mass = 6.64×10−27 kg6.64\times10^{-27}\,\text{kg}) is projected towards a metal plate that is at a potential 1.2 kV1.2\,\text{kV} higher than the point of projection. Determine the minimum initial speed required for the α\alpha-particle just to reach the plate.
