can anyone help me with this physics problem?
i am having a lot of trouble with this type of problem. thanks to anyone who is able to help. i will choose Best Answer.
Calculate the ratio of the magnitude of the gravitational force between a 3.200- kg mass on the surface of the earth due to the sun to that due to the moon. The mass of the sun is 1.99e+30kg and the distance from the center of the sun to the surface of the earth is 1.50e+08km
can anyone show me the steps and correct answer?

Let m = mass of the object
Ms = sun's mass
Mm = moon's mass
rs = distance of the mass from the sun
rm = distance of the mass from the moon
Fs = force by the sun,
Fm = force by the moon
Fs = G Ms m/rs^2
Fm = G Mm m/rm^2
Fs/Fm = (Ms/Mm) * (rm/rs)^2
Putting Ms = 1.99 * 10^30 kg, Mm = 7.35 * 10^22 kg
rs = 1.50 * 10^8 km, rm = 4.07 * 10^5 km,
Fs/Fm = 199.33
Ans: 199.33 : 1
It is approximately 200:1
(Does the question give the value of moon's mass and the distance of moon's center from Earth's surface?)
