An electric field around two charged objects is shown. Two spheres next to each other. Vectors perpendicular to each surface spread out and go to the other charge. The vectors are from the charge on the left, labeled X, and to the other charge, labeled Y. The vectors on the opposite sides of the charges are not bent. What are the charges of objects X and Y? X: negative Y: positive X: positive Y: positive X: negative Y: negative X: positive Y: 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^.
