The Total solution for NCERT class 6-12
Calculate the force of gravitation betweenthe earth and the Sun, given that the mass of the earth = 6 × 1024 kg and of the Sun =2 × 1030 kg. The average distance between thetwo is 1.5 × 1011 m.
Accordingto the universal law of gravitation, the force of attraction between the Earthand the Sun is given by:
Where,
MSun = Mass of the Sun =2 × 1030 kg
MEarth = Mass of the Earth= 6 × 1024 kg
R = Average distance between the Earthand the Sun = 1.5 × 1011 m
G = Universal gravitational constant = 6.7 ×10−11 Nm2 kg−2
