By moving a 20 nC charge from point A to point B, you determine that the electric potential at B is 100 V . Part A What would be the potential at B if a 40 nC charge were moved from A to B

We always determine the potential with respect to some reference point. Let the potential at A be zero. If the potential at B is V, then work done to bring charge q from A to B = qV

which is the electric potential energy.

If instead we use some charge Q, the electric potential energy will be QV, but the electric potential will always be V.

The potential at B would still be 100 V even if 40 nC were moved from A to B.

Why wouldn't there be electric potential changes?

Because the electric potential is defined by the work done on the system.
Because the value of nC does not interfere with the electric potential.
Because the work on the system would be the same even with the transfer of nC.

In the case shown in the question, we can consider that the electric potential at A is equal to zero. This allows the work performed to be constant and not change the electrical potential at B.
