Question

Calculate the magnitude of the gravitational force between the earth and a 10kg object on its surface.( Mass of the earth is 6 ×10^24 kg and radius of the earth is 6.4 ×10^6 m) ii) Write the value of the universal gravitational constant on moon.

Answer 1

Explanation:

ANSWER

Given :       Mass of earth    M=6×1024 kg

                   Mass of object    m=1 kg

                  Radius of earth       R=6.4×106 m 

Force of gravitation between them, F=R2GMm

F=(6.4×106)26.67×10−11×(6×1024)×1=9.77 N
