Question

# In the Newton's gravitational law, $$F = \dfrac{G M m}{d^{2}}$$, the quantity G:

A
depends on the value of g at the place of observation
B
is used only when the earth is one of the two masses
C
is greatest at the surface of the earth
D
is universal constant in nature

Solution

## The correct option is D is universal constant in natureFrom Newton's law of gravitation, the force of attraction between bodies  $$F= \dfrac{GMm}{r^2}$$.Here G is called the universal gravitational constant as the value of G is same whether the measurements are made on earth or any other planet.The value of gravitational constant is $$G = 6.67 \times 10^{-11} N/m^{2}$$.Physics
