Answer:
Explanation:
Well this really depends on you dude; this question asks for your opinion.
But personally I disagree with this because I like to use different ways to find the answer or in this case describe the entire universe. This is because I can use different variables to solve for the unknown.
If you agree, you can say something like I can memorize this equation or something along the lines.
Let the mass of planet and moon be Mp and Mn respectively.
And the distance between them is "r"
Then according to Newton's law of gravitation,
The force with which the planet and the moon attract esch other is
1) directly proportional to the product of their masses i.e. Mp * Mn
2) inversly proportional to the square of the distance between them i.e r ^2
Therefore,F =. G (Mp* Mn)/r^2
Where,G is gravitational constant
<span>I found out F2 and its correct just need help in solving the other parts </span>
<span>F2 = 4.5 N </span>
