Question

What will be the gravitational force between earth and an object of 1 kg placed on its surface. Here the mass of earth is 6 into 10 to the power 24 kg do distance from the object to the earth's surface is 6400km

Answer 1

Answer:

We know gravitation force F=R2GMm=(6.4×106)26.67×10−11×6×1024×1=9.8N 

Where M = mass of the earth, m = mass of the object and R = radius of earth
