To understand Newton's law of gravitation and the distinction between inertial and gravitational masses.1. Two particles are separated by a certain distance. The force of gravitational interaction between them is F0. Now the separation between the particles is tripled. Find the new force of gravitational interaction F1.Express your answer in terms of F0.F1=2. A satellite revolves around a planet at an altitude equal to the radius of the planet. The force of gravitational interaction between the satellite and the planet is F0. Then the satellite moves to a different orbit, so that its altitude is tripled. Find the new force of gravitational interaction F2.Express your answer in terms of F0.F2=3. A satellite revolves around a planet at an altitude equal to the radius of the planet. The force of gravitational interaction between the satellite and the planet is F0. Then the satellite is brought back to the surface of the planet. Find the new force of gravitational interaction F4.Express your answer in terms of F0.F4=4. Two satellites revolve around the Earth. Satellite A has mass m and has an orbit of radius r. Satellite B has mass 6m and an orbit of unknown radius rb. The forces of gravitational attraction between each satellite and the Earth is the same. Find rb. Express your answer in terms of r. rb=5. An adult elephant has a mass of about 5.0 tons. An adult elephant shrew has a mass of about 50 grams. How far r from the center of the Earth should an elephant be placed so that its weight equals that of the elephant shrew on the surface of the Earth? The radius of the Earth is 6400 km. (1ton=103kg.)Express your answer in kilometers. r=The table below gives the masses of the Earth, the Moon, and the Sun. Name Mass (kg)Earth 5.97×1024Moon 7.35×1022Sun 1.99×1030The average distance between the Earth and the Moon is 3.84×108m. The average distance between the Earth and the Sun is 1.50×1011m. Use this information to answer the following questions.6. Find the net gravitational force Fnet acting on the Earth in the Sun-Earth-Moon system during the new moon (when the moon is located directly between the Earth and the Sun).Express your answer in newtons to three significant figures. Fnet=7. Find the net gravitational force Fnet acting on the Earth in the Sun-Earth-Moon system during the full moon (when the Earth is located directly between the moon and the sun).Express your answer in newtons to three significant figures. Fnet=
