Question

Two charges q, = 3.0 HC and q2 = -4.0 MC initially are separated by a distance ro = 2.0 cm. An external agent
moves the charges until they are r, = 5.0 cm apart.
How much work is done by the electric field in moving the charges from rotor,? Is the work positive or
negative?
(it) How much work is done by the external agent in moving the charges from rotor,? Is the work positive or
negative?
(fit) What is the potential energy of the initial state where the charges are ro = 2.0 cm apart?
(rv) What is the potential energy of the final state where the charges are r, = 5.0 cm apart?
() What is the change in potential energy from the initial state to the final state?​
