9 Questions
In an electric field, if the force and the direction of displacement are opposite, what can be said about the work done and the change in electric potential energy?
Work is positive and electric potential energy increases
What type of motion of a charge relative to the direction of the force aids in understanding changes in electric potential energy?
Circular motion
What characteristic of charges makes determining the sign of the change in potential energy confusing?
Sign (positive or negative)
In a uniform electric field, what does it mean if the net work done by the Coulomb force is zero?
The charge has returned to its initial position
For a pair of charges q and q0, what type of force is the Coulomb force considered to be?
Conservative force
What factor(s) determine(s) the work done by the Coulomb force for a pair of charges q and q0?
Both initial and final radial positions
If a test charge returns to its initial location in an electric field, what can we conclude about the net work done?
Net work is zero
Under what circumstances is the net work done by Coulomb force zero?
The charge returns to its initial position.
What aspect allows us to differentiate between positive and negative changes in potential energy for charges?
Signs (positive or negative) associated with the charges.
