Homework Help: PHYSICS CIRCULAR MOTION GRAVITATIONAL CONSTANT

Posted by Jaylee on Sunday, November 14, 2010 at 1:08pm.

Three masses are arranged in an (x, y)
plane.
7 kg (-3,1)
8 kg (0,0)
9 kg (1,2)

a) What is the magnitude of the resulting force on the 8 kg mass at the origin? The universal gravitational constant is 6.6726 10^−11 N m^2/kg^2. Answer in units of N.

b) What is the angle of the resultant force on the 9 kg mass at the origin?
