1
On which of the following does the amount of work required to move a charge in an electric field depend?
Only the change in potential
Only the path traveled
Both the potential and the path traveled
Neither the potential nor the path traveled
Only the magnetic field
Explanation
Work done by electric field is defined:
Notice that the only variable in the equation is the potential, so this is the only quantity on which work depends.
