Hi there hoping a Physics tutor could support me on problems 1-5. It would really mean much thanks so much. Heavily struggling in this circular motion stuff. (:

1. What is the weight of a 90 kg boy on earth (g=9.8 N/kg)? How about on the moon (g=1.6 N/kg)? On Jupiter (g=29.4 N/kg)? 2. An 75 kg astronaut has a weight of 622 Newtons while he is in outer space. What is the strength of the gravitational field at this spot? 3. If two objects have a 2 N gravitational force between them, how strong would the gravitational force be if the objects were moved to a position that was three times further away than the original separation? What if the position was y the original separation? 4. Object A feels 3 N of gravitational force from Object B, if Object B is replaced by Object C, where Object C has a mass five times larger than Object B, how much gravity would Object A feel from Object C? What would the force be on Object A if you doubled the mass of Object A, too?5. A young couple is dancing closely (distance between their centers of mass is 30 cm) and the boy feels attracted to the girl. Thinking this attraction is due to gravity, he wants to calculate the attractive force between him and his date. If her mass is 58 kg, and his mass is 72 kg, what is the gravitational force between the two
