Question

Which of the following quantities do not depend on the choice of zero potential or zero potential energy?

• A. Potential at a point
• B. Potential difference between two points
• C. Potential energy of a two-charge system
• D. Change in potential energy of a two-charge system

Answer 1

Answer: (B), (D)

Potential difference between two points
Change in potential energy of a two-charge system

For A:

Point Potential Needs a Reference.

Hence False

For B:

Potential Difference, Reference Potential gets cancelled/Subtracted.

Hence True

For C:

Potential from 2 charged points, Reference Potential gets included in the Final energy calculation.

Hence False

For D:

Potential Difference is the deciding factor, Reference Potential gets cancelled/Subtracted.

Hence True
