Question

An electron that accelerates from a point near a collection of positive source charges toward a point near a collection of negative source charges experiences

• A. A decrease in electrical potential energy as it moves toward a region at a lower electric potential
• B. A decrease in electrical potential energy as it moves toward a region at a higher electric potential
• C. An increase in electrical potential energy as it moves toward a region at a lower electric potential
• D. An increase in electrical potential energy as it moves toward a region at a higher electric potential
• E. No change in electrical potential energy

Answer 1

Answer: (C)

An increase in electrical potential energy as it moves toward a region at a lower electric potential

Electric potential energy of a system of charges means work done to create the system of charges.

When electron moves towards collection of negative charges we will have to do more work and more to take the electron towards negative charges , it is due to repulsion force that negative charges exert on electron.therefore potential energy increases towards the region of negative charges or lower electric potential .
