Increases
Decreases
Remains constant
Cannot be determined
If the electric potential increases, the work done by the external force must increase to move the positive charge against the electric field.

Q
Q: If the electric potential at a point is increased, what happens to the work done by an external force on a positive charge moved to that point?
Solution: If the electric potential increases, the work done by the external force must increase to move the positive charge against the electric field.
Steps: 4
Step 1: Understand what electric potential means. It is the amount of work needed to move a positive charge to a point in an electric field.
Step 2: Recognize that when electric potential increases, it means that more work is required to move a positive charge to that point.
Step 3: Realize that an external force is needed to move the charge against the electric field. This external force does work on the charge.
Step 4: Conclude that if the electric potential increases, the external force must do more work to move the positive charge to that point.
