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 V`, an electron is moving towards `A` form `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 4eV K. E. at B

D

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

Text Solution

Verified by Experts

The correct Answer is:
A, C
An electron naturally move from low potential to high potential to make it move from `B to A` it should have minimum `K.E --e(V_A-V_B)=4ev`.
