(a) Find the magnitude of the gravitational force (in N) between a planet with a mass of 6.75 ✕ 1024 kg and its moon, with a mass of 2.30 ✕ 1022 kg, if the average distance between their centers is 2.60 ✕ 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.)

Please give the detailed formula, if I have a worked example, then I can plug my numbers into it and understand it.
