Question

(i) State the universal law of gravitation.
(ii) Express it in a mathematical form. (Explain the symbols used.)
(iii) State the value of universal gravitation constant in S.I. unit.

Answer 1

Answer:

universal law of gravitation

Explanation:

Every object in the universe attract every other object with a which is direct proportional to their product of their masses and inversely proportional to their square of mean distance

Answer 2

Answer

1.The law of gravitation formulated by Newton states that the force of attraction between any two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

2.F=Gm1m2/r^2

Here g is a constant called universal gravitational constant

3. The value of universal gravitational constant in SI unit is 6.67 into 10^- 11 Newton metre^2/ kg^2
