Instructor gave us an idea of what each problem on the test would be about so we can prepare, I
wrote as many notes and diagrams as I could. Please help me by providing any relevant
equations that may be needed to solve these types of problems, and an example of simple type of
problem like this that may be asked would be hugely beneficial. We are allowed 1 page cheat
sheet so anything I can put on there to help me with a problem like this would be great. I really
need to do well on this test! 'll rate you positively for your time and effort. Thanks so much for
your helpl 0 Sance etvear Force applke on each other
Solution
m 1 = mass of left sphere
m 2 = mass of right sphere
d = distance between centers of spheres = r 1 + r 2
force applied on each other is given as
F = G m 1 m 2 /d 2
F = G m 1 m 2 /(r 1 + r 2 ) 2
