Answer 1

Here, are your questions

1) The distance between a 40-kg person and a 30-kg person is 2 m. What is the magnitude of the gravitational force each exerts on the other. Universal constant = 6.67 x 10-11 N m2/ kg2

2) The distance between Earth and Moon (r) is 3.84 x 108 m. What is the magnitude of gravitational force each exerts on the other?

3) Calculate the force of attraction between two metal spheres each of mass 90 kg. if the distance between their centers is 40 cm.
