Potential at a point A is 3 volt and at ...

Potential at a point A is 3 volt and at a point B is 7 volt, an electron is moving towards A from B. Then:

A

It must have some K.E at B to reach A

B

It need not have any K.E at B to reach A

C

to reach A it must have more than or equal to 4 eV K.E at B.

D

when it will reach A, it will have K.E. more than or at least equal to 4 eV if it was relased from rest at B.
