Question

Explain Newton law of gravitation.​

Answer 1

Answer:

every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. 

hope it helps

Answer 2

$\sf\bold\purple{{QUESTION:-}}$

✓✓Explain Newton's law of gravitation.

$\sf\bold\green{{ANSWER:-}}$

According to this law a force of attraction between two body is directly proportional to the product of their masses and inversely proportional to the square of distance between the two bodies.

$\sf\:Force ∝ product\:of\:masses\:of\:bodies$

$\sf\:F∝m1×m2$------------------------(i)

$\sf\:Force∝\dfrac{1}{distance^2}$

$\sf\:F∝\dfrac{1}{r^2}$------------------(ii)

From eq (i) and (ii), we get

$\sf\:F∝\dfrac{m1\:m2}{r^2}$

$\sf\:F=G\dfrac{m1\:m2}{r^2}$

Where G= universal gravitational constant

$\sf\:G=6.67×{10}^{-11}\:N{m}^{2}/k{g}^{2}$
