Question

a. Find the magnitude of the gravitational force (in N) between a planet with mass 6.50 ✕ 1024 kg and its moon, with mass 2.45 ✕ 1022 kg, if the average distance between their centers is 2.50 ✕ 108 m.b. What is the moon's acceleration (in m/s2) toward the planet? (Enter the magnitude.)c. What is the planet's acceleration (in m/s2) toward the moon? (Enter the magnitude.)

Answer 1

Answer:

a. $1.70\times 10^{20} N$ b. $6.94\times 10^{-3}m/s^2$ c. $2.62\times 10^{-5} m/s^2$

Explanation:

Use Gravitational Force:

$F= G\frac{Mm}{r^2}$

Use values given to have the results.

b.

$g=\frac{F}{m}$

Use m as the mass of the Moon. Using values of a. and m you have the answer.

c.

$g = \frac{F}{M}$

Use M mass of the planet. Use value of a and Mass of Planet.
