Explanation:
Detailed explanation-1: -The gravitational force on a body of mass 5 kg at the surface of the earth is 50 N.
Detailed explanation-2: -Answer and Explanation: The gravitational force of the Sun on the Earth is 3.52×1022 3.52 × 10 22 Newtons.
Detailed explanation-3: -Calculate the weight (in newtons) of a 5.0-kilogram backpack on Earth (g = 9.8 N/kilogram). Solution: The same backpack weighs 8.2 newtons on Earth’s moon.
Detailed explanation-4: -The mass of the earth =6×1024 kg and of the Sun =2×1030 kg. The average distance between the two is 1.5×1011 m. As given, mass of the sun m1=2×1030 kg. Mass of the earth m2=6×1024 kg. =3.57×1022 N. Therefore, the force of gravitation between the sun and the earth is 3.57×1022 N. 10-Oct-2022
