Potential atapoint $A$ is $3 $ $ volt$ and atapoint $B$ is $7$ $volt$,an electron is moving towards $A$ from $B.$
- 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
$A$ and $C$ both
