In the assembly as shown below, the potential differences across the plated is 4 volts. A positive particle of charge +4e is projected from the negative plate with an initial kinetic energy of 4eV and the negative particle of charge (-2e) is projected from the positive plate.Both the particle reach point A with zero kinetic energy. Find the initial energy of the negative particle in eV.
