Question

11. What is the gravitational potential
energy of the Earth and Sun? The
Earth to Sun distance is around
150 million km. The mass of the Earth
is 5.9 x 1024 kg and mass of the Sun is
1.9 x 10 kg
Ans: U= -49.84 x 1032 Joule​

Answer 1

Mass of the Earth ME = 5.9 × 1024 kg Mass of the Sun M = 1.9 × 1030 kg Distance between the Sun and Earth r = 150 million km; r = 150 × 109 m Gravitational constant G = 6.67 × 10-11 Nm2 kg-2
