Question

The mass of the moon is 1% of mass of the earth.the ratio of gravitational pull of earth on moon to that of moon on earth will be

Answer 1

⭐⭐⭐ Hey mate!!⭐⭐⭐

__________________________________________________________

⚡♐The gravitational pull on earth by moon is same as that of pull on moon by earth this is because while calculating force we make use of masses of both objects .

so F12=F21 that is 1:1

⚡⚡Your answer is 1:1

Hope it will help you...✌️✌️

Answer 2

Answer:

1:1

Explanation:

m₁ =  Mass of Earth

m₂ =  Mass of Moon = 0.01 m₁

r = Distance between the Earth and Moon

G = Gravitational constant

Force of Earth on Moon

$F_{em}=G\frac{m_1m_2}{r^2}\\\Rightarrow F_{em}=G\frac{m_10.01 m_1}{r^2}\\\Rightarrow F_{em}=G\frac{0.01m_1^2}{r^2}$

Force of Moon on Earth will be the same according to the third law of motion

$F_{me}=G\frac{m_1m_2}{r^2}\\\Rightarrow F_{me}=G\frac{m_10.01 m_1}{r^2}\\\Rightarrow F_{me}=G\frac{0.01m_1^2}{r^2}$

Dividing the equations we get

$\frac{F_{em}}{F_{me}}=\frac{G\frac{0.01m_1^2}{r^2}}{G\frac{0.01m_1^2}{r^2}}\\\Rightarrow \frac{F_{em}}{F_{me}}=1:1$

The ratio of gravitational pull of earth on moon to that of moon on earth will be 1:1.
