The mass of the earth is 5.97 x 1024 kg. Its order of magnitude will be
1025
24
1024
25
The order of the magnitude is 1025. Since, the numerical value 5.97 > 3.2, thus
Order of magnitude = 101 × 1024 = 1025
Mass of earth is (5.97×1024) kg and mass of moon is (7.35×1022) kg. What is the total mass of the two?
Question 3 What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6×1024 kg and radius of the earth is 6.4×106 m)
The earth (mass=6×1024kg) revolves around the sun with angular velocity 2×10−7rad/s in a circular orbit of radius 1.5×108 km. The force exerted by the sun on the earth in newtons is
