A particle of mass 1g and charge 2 C is released from a point A in a region of space containing electric field. Its speed is measured to be 2 `m//s` when it passes a point B some distance away from A. Potential difference the two points A and B is

1 mV

2mV

4 Mv

Both the points are a the same potentials
