A +3.0 µC point charge is 0.030 m from another point charge and experiences an attractive force of 180 N. What is the magnitude of the other charge?
+6 uC or -6 uC
What is the change in electric potential difference when +30.0 J of work is done on a charge of +0.010 C?
-3000 V or +3000 V
+6 uC or -6 uC
What is the change in electric potential difference when +30.0 J of work is done on a charge of +0.010 C?
-3000 V or +3000 V

1) If the positive charge experiences an ATTRACTION, that means that the other charge is negative. So your answer would be -6uC.
Like charges repel, opposite charges attract.
#2) W = qV
Plug the numbers in and you get a positive outcome. Therefore the answer would be +3000V
