An equilateral triangle 10.0m on a side has a 1.00kg mass at one corner, a 2.00kg mass at another corner, and a 3.00kg mass at the third corner.
Find the magnitude of the net force acting on the 1.00kg mass.
Find the direction of the net force acting on the 1.00kg mass.

Use Newton's universal law of gravity and add the two forces as vectors. They will be 60 degrees apart, and one will be 1.5 times the other.
