NCERT Exercise

Calculate the force of gravitation between the 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 the two is 1.5 × 1011 m.

According to question,


MSun = Mass of the Sun = 2 � 1030 kg
MEarth = Mass of the Earth = 6 � 1024 kg
R = Average distance between the Earth and the Sun = 1.5 � 1011 m
From Universal law of gravitation,
