What is the kinetic energy of the particle

Reference no: EM13238289

A particle of charge +9.2 ?C is released from rest at the point x = 55 cm on an x axis. The particle begins to move due to the presence of a charge Q that remains fixed at the origin. What is the kinetic energy of the particle at the instant it has moved 12 cm if

(a) Q = +61 ?C and

(b) Q = -61 ?C?
