016 (part 1 of 2) 10.0 points Objects with masses of 317 kg and 225 kg are separated by 0.345 m. A 20.7 kg mass is placed midway between them. 225 kg 317 kg 20.7 kg O 0.345 m Find the magnitude of the net gravitational force exerted by the two larger masses on the 20.7 kg mass. The value of the universal gravi- tational constant is 6.672 x 10 N - m/kg?. Answer in units of N. 017 (part 2 of 2) 10.0 points Leaving the distance between the 317 kg and the 225 kg masses fixed, at what distance from the 225 kg mass (other than infinitely remote ones) does the 20.7 kg mass experience a net force of zero? Answer in units of m
