Objects with masses of 149 kg and 1/3 kg are separated by 0.332 m. A 51.6 kg mass is
placed midway between them.
PART 1: Find the magnitude of the net gravitational
force exerted by the two larger masses on the
51.6 kg mass. The value of the universal gravi-
tational constant is 6.672 x 10-11 N. m2/kg2.
Answer in units of N. PART 2: leaving the distance between the 149 kg and the 773 kg masses fixed at what distance from the 773 kg mass (other than infinitely remote ones) does the 51.6kg mass experience a net force of zero? Answer in units of m.
