Charges in Electric and magnetic fields

The work done = Fd = Eqd = Vq
Hence the gain in kinetic energy = Vq
The motion of the charged particle can also be determined using the link between work done and change in energy.
A negatively charged particle is accelerated in the opposite direction to the electric field.

The analysis of the motion is similar to that of a particle of mass m moving in a gravitational field with a uniform velocity in one direction and a uniform acceleration in a perpendicular direction
