Can you please explain and give me a solution for all

PRACTICE What is the effect on a gravitational 1) Two masses are attracted by a force of 20 newtons. Is gravitational force increased or system if ... decreased? a. What would the force between them be if both masses were tripled? .. 3x both masses 1. " the distance b. What would the force between them be if the distance separated them N 4x distance 1/2 one mass and 1/2 distance were doubled? 3 . 2x one mass and 3x the other 3 . 3x one mass 2 ) An astronaut with a mass of 50 kilograms is standing on Earth's surface. Calculate his weight while on the Earth's surface. 4 . 1/2 distance and 2x one mass 4. 2x distance The astronaut moves to an altitude that is one Earth radius above the surface of the Earth. Calculate his weight at this altitude. 3x both masses; 4x distance 5 . 1/2 one mass; double the other SY
