Not what you're looking for?
Problem 1
A charge is moved from one place to another in an electric field. In which of the following situations will the change in potential energy be NON-ZERO?
the charge is only moved perpendicular to all electric field lines that it crosses
the charge remains unmoved
the charge is moved along an equipotential surface
the charge is moved to the left by 5 mm and then back to the right by 5 mm
the charge is moved along an electric field line, in the opposite direction as the field
Problem 2
Consider an isolated point charge which has Q = +5 Coulombs. Evaluate the following statements about the electric field and potential of the charge.
the potential is zero everywhere in the region around the charge
electric potential is defined as the electric force per unit charge
spherical equipotentials surround the charge
the electric field at a radius of r = 3 cm has a direction which points inward towards the charge
the potential at a radius of r = 3 cm has a direction which points inward towards the charge
Problem 3
Consider a point charge +Q and another point charge -Q separated by a certain distance in empty space. Which of the following statements are true about the electric field and electric potential in this situation?
electric field lines go from -Q to +Q
at the midpoint between +Q and -Q, the force on any charge is zero
at the midpoint between +Q and -Q, the electric field is zero
at the midpoint between +Q and -Q, the electric potential is zero
as you get closer to +Q, the potential increases
