Question 1

As shown in the figure, three small charges are equally spaced on the arc of a circle that is centered at the charge Q, where Q = +23 nC and all the other quantities are accurate to two significant figures. What is the magnitude of the net electric force on the charge Q due to the other three charges? (k = 1/4πε0 = 9.0 × 109 N ∙ m2/C2)



◦ 2.6 × 10-4 N
◦ 1.7 × 10-4 N
◦ 3.1 × 10-4 N
◦ 2.1 × 10-4 N

Question 2

As shown in the figure, the charge Q is midway between two other charges. If what must be the charge q1 so that charge q2 remains stationary as Q and q1 are held in place?



◦ 7.5 nC
◦ 15 nC
◦ 60 nC
◦ 30 nC
