Question

1. Objects with masses of 193 kg and 348 kg are separated by 0.328 m. A 61.2 kg mass is placed midway between them.Find the magnitude of the net gravitational force exerted by the two larger masses on the 61.2 kg mass. The value of the universal gravitational constant is 6.672 × 10−11 N · m^2 /kg^2 . Answer in units of N.
2. Leaving the distance between the 193 kg and the 348 kg masses fixed, at what distance from the 348 kg mass (other than infinitely remote ones) does the 61.2 kg mass experience a net force of zero? Answer in units of m.
