A particle $($charge $=+1\mathrm{.}0$ mC$)$ moving in a region where only electric forces act on it has a kinetic energy of $2\mathrm{.}0$ J at point A$.$ The particle subsequently passes through point B which has an electric potential of $+1\mathrm{.}5$ kV relative to point A$.$ Determine the kinetic energy of the particle as it moves through point B$.$
