A particle of charge +7 .5C is released from rest at the point x = 60 cm

A particle of charge +7 .5μC is released from rest at the point x = 60 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 40 cm if

(a) Q = +20μC and

(b) Q = ?? 20μC?
