Explanation / Answer

for the gravitational forces

magnitude of the gravitational force = G * m1 * m2/d^2

magnitude of the gravitational force = 6.673 *10^-11 * 9 *10^24 * 2.4 *10^22/(2.7 *10^8)^2

magnitude of the gravitational force = 1.98 *10^20 N

the magnitude of the gravitational force is 1.98 *10^20 N

moon's acceleration = Force/mass of moon

moon's acceleration = 1.98 *10^20/(2.4 *10^22)

moon's acceleration = 0.0083 m/s^2

--------------------

planet's acceleration = force/mass of earth

planet's acceleration = 1.98 *10^20/(9 *10^24)

planet's acceleration = 2.2 *10^-5 m/s^2
