Two masses, m1 and m2 are separated by a distance, r. The force of attraction between the two masses is F. If the original force is 20N and both masses quadruple while the r decreases to ¼ of the original distance:
A) how much would F change?
B) what will be the new force?

Two masses m1 and m2 are located a distance r apart and are initially at rest. Due to the attractive gravitational force, the two masses will move towards each other. Find the velocity of each mass when they are located a distance d apart. You are given G. (Answer: For mass m1: v1 = m2sqrt(2G(1/d-1/r)/(m1 + m2)))

A certain binary star system consists of two stars with masses m1 and m2, separated by a distance b. A comet, originally nearly at rest in deep space, drops into the system and at a certain point in time arrives at the midpoint between the two stars. For that moment in time, find its velocity, v, symbolically in terms of b, m1, m2, and fundamental constants. p
