Question

What gravitational force does the moon produce on the Earth is their centers are 3.88 x 10^8 m apart and the moon has a mass of 7.34 x 10^22 kg?

Answer 1

Answer:

The gravitational force is $1.942\times10^{20}\ N$

Explanation:

Given that,

Mass of moon $M=7.34\times10^{22}\ Kg$

Distance $d=3.88\times10^{8}\ m$

We need to calculate the gravitational force

Using formula of gravitational force

$F_{G}=\dfrac{GmM}{d^2}$

Where m = Mass of earth

M =Mass of moon

d = distance

Put the value into the formula

$F_{G}=\dfrac{6.67\times10^{-11}\times7.34\times10^{22}\times5.972\times10^{24}}{(3.88\times10^{8})^2}$

$F_{G}=1.942\times10^{20}\ N$

Hence, The gravitational force is $1.942\times10^{20}\ N$
