Explanation:

It is given that,

Mass of moon, $m=7.35\times 10^{22}\ kg$

Radius of circle, $r=3.82\times 10^{5}\ km=3.82\times 10^{8}\ m$

The time required for one revolution is 27.3 days, t = 27.3 days

1 day = 86400 seconds

27.3 days = 2358720 seconds

Let v is the speed of moon around the circular path. It is given by :

$v=\dfrac{2\pi r}{T}$

$v=\dfrac{2\pi \times 3.82\times 10^{8}\ m}{2358720\ s}$

v = 1017.57 m/s

Let F is the centripetal force acting on the moon. It is given by :

$F=\dfrac{mv^2}{r}$

$F=\dfrac{7.35\times 10^{22}\ kg\times (1017.57\ m)^2}{3.82\times 10^{8}\ m}$

$F=1.99\times 10^{20}\ m/s^2$

So, the centripetal force that must act on the moon is $1.99\times 10^{20}\ m/s^2$ . The gravitational force that the earth exerts on the moon at that same distance is also equal to $1.99\times 10^{20}\ m/s^2$ . Hence, this is the required solution.
