B.) Calculate the force between a +5 µC test point charge and this source charge at a distance of 2.00 cm. (µC = 1.0 × 10–6 C)
c.) If the test charge were moved closer to the source charge, would the change in its potential energy be positive, negative or zero? Explain.

I've already done the work and got the answer for B. I'm just confused on how I would figure out the answer to C. Help??

shamim · Answer

wt is ur source charge

shamim · Answer

if ur source charge is positive then potential energy will increase

shamim · Answer

if source charge is negative then potential energy will decrease
