Question 16 Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth = 6 × 10 24 kg and of the Sun = 2 × 10 30 kg. The average distance between the two is 1.5 × 10 11 m.Class 9 - Science - Gravitation Page 144

_/\_Hello mate__here is your answer--

GIVEN:---
M1 = Mass of the Sun = 2 × 10^30 kg
M2 = Mass of the Earth = 6 × 10^24 kg
R = Average distance between the Earth and the Sun = 1.5 × 10^11 m
G = 6.7 × 10^−11 Nm^2 kg^−2
According to the universal law of gravitational ,
F = G× M1 × M2/ r^2
(Put the values of all quantities, we get)
=6.7×10^−11×2×10^30×6×10^24/(1.5×10^11)^2
= 3.57 × 10^22 N
Hence, the force of gravitation between the Earth and the Sun is
3.57 × 10^22 N
I hope, this will help you.☺
Thank you______❤

Answer:
mass of earth = 6 × 10²⁴ Kg
mass of sun = 2 × 10^30 Kg
distance between earth and sun = 1.5 × 10¹¹ m
F = GMm/r²
= 6.67 × 10-¹¹ × 6 × 10²⁴ × 2 × 10^30/(1.5 × 10¹¹)²
= { 6.67 × 6 × 2/2.25} × 10¹³ × 10^30× 10-²²
= 35.57 × 10²¹ N
= 3.557 × 10²² N
