The figure shows two electric charges q1 and q2, the distance r and the Coulomb forces. If q1 = 2q2, which of the following statements is correct? A. The force F1 is exerted by the load q1. B. The force F1 is exerted by the load q2. C. The measure of F1 is twice the measure of F2. D. The loads are positive. Q. Loads are negative.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
