Question

Ch. 24 q.5 

Part be is supposed to be in J, thank you!

Two point charges Q, = +5.40 nC and Q, = -2.10 nC are separated by 45.0 cm.
(a) What is the electric potential at a point midway between the charges?
132
V
(b) What is the potential energy of the pair of charges?
|-0.00000040 x
Calculate the electric potential from one charge at the location of the other charge. How is that electric potential related to the potential energy? J
What is the significance of the algebraic sign of your answer?
O Positive work must be done to separate the charges.
O Negative work must be done to separate the charges.
