Which one of the following statement is true for the relation F = Gm1m2/r^2 ?

Question

Which one of the following statement is true for the relation \(F = \frac{Gm_1m_2}{r^2}\)?

(a) The quantity G depends on the local value of acceleration due to gravity g.

(b) The quantity G is greatest at the surface of the earth.

(c) The quantity G is smallest at the surface of the earth.

(d) The quantity G is a universal constant

Answer 1

Correct option is (d) The quantity G is a universal constant

In relation, \(F = \frac{Gm_1m_2}{r^2}\) the force between two bodies and G is universal constant. It does not depend upon the constitution of bodies or any other factor.

Its value is 6.67 x 10^-11 N-m²/kg².
