Answer to Question #146757 in Physics for its me gel

Question

Solve each problem and provide the complete solution.
note: topic is all about Gravitational force

Two objects, A and B, have weights of 5kg and 6kg respectively. If they are 2m away from each other, what is the force of attraction between them?

Answer 1

We can find the force of attraction between the object A and B from the Newton’s law of universal gravitation:

$$F=G\dfrac{m_Am_B}{r_{AB}^2},$$ $$F=6.672\cdot10^{-11}\ \dfrac{Nm^2}{kg^2}\dfrac{5\ kg\cdot 6\ kg}{(2\ m)^2}=5\cdot10^{-10}\ N.$$

Answer:

$F=5\cdot10^{-10}\ N.$
