The elctric field between two metal plates is assumed to be uinform at 2*10^4V/m.A positively charged particle has displacement of 0.2m in the direction of the field .What is the change in PE if it carries a charge of +3e?e=1.6*10^-19C.

Question

Shivam Chopra · Answer

Electric field b/w the plates = σ/ϵ = 2 * 10 4 Vm -1 Charge on particle = +3e = 4.8 * 10 -19 C So, force on particle = 4.8 * 2 * 10 -15 = 9.6 * 10 -15 N As, the particle moves in the direction of field, so, work is done by the system. So, potential energy will be –ve. So, PE = - F * d = - 9.6*10 -15 * 0.2 = - 1.92 * 10 -15 J. Please approve it if you like.
