Question 1

Two equally charged tiny spheres of mass 1.0 g are placed 2.0 cm apart. When released, they begin to accelerate away from each other at What is the magnitude of the charge on each sphere, assuming only that the electric force is present?  (k = 1/4πε0 = 9.0 × 109 N ∙ m2/C2)
◦ 75 nC
◦ 95 nC
◦ 120 nC
◦ 140 nC

Question 2

One point charge +Q is placed at the center of a square, and a second point charge -Q is placed at the upper-left corner of the square.  It is observed that an electrostatic force of magnitude 2.0 N acts on the positive charge at the center.  Now a third charge -Q is placed at the lower-left corner of the square, as shown in the figure. What is the magnitude of the net force that acts on the center charge now?



◦ 4.0 N
◦ 2.8 N
◦ 0.0 N
◦ 5.3 N
