Which of the following statements about electric potential energy is not correct?
- The electric potential energy of a positively charged particle increases when it moves to a point of higher potential
-
The electric potential energy of a negatively charged particle increases when it moves to a point of lower potential
- The electric potential energy of a positively charged particle decreases when it moves to a point of higher potential
- The work done in taking a charged particle around a closed path in an electric field is zero.
The correct answer is: B
Explanation
The potential energy for a positive charge increases when it moves against an electric field
And decreases when it moves with the electric field;
The opposite is true for a negative charge. Unless the unit charge crosses a changing magnetic field, its potential at any given point does not depend on the path taken.
