Q. A test charge is moved from a lower potential point to a higher potential point. the potential energy of test charge will

1. remains same

2. increase

3. decrease

4. become zero

Video Time: 0 Min 1 Sec

2. increases

Let the lower potential is V1 and the higher one is V2. A +ve charge, let it be q, is shifted from V1 to V2.

The initial PE of q was q*V1 and the final is q*V2, so the change is

q*V2 - q*V1 = q(V2 - V1)

Since V2 > V1, the result is +ve

Which means the potential energy will increase.

As explained here by sir... Watch again around this time. (snap attached)
