A particle having a charge q=3x10^-5 C moves from point a to b, a total linear distance of .5 meter.If the mass of the charge is 5x10^-5 kg and the electric field is uniform and in the direction of a to b E=200 N/C what is the increase in energy in eV?in Joules?How fast is the particle going at point b?
