Question

Give the value of universal gravitational constant.

Answer 1

1. Universal Gravitational Constant: The value of the universal gravitational constant(G) is $\mathbf{6}\mathbf{.}\mathbf{67}\mathbf{\times }{\mathbf{10}}^{\mathbf{-}\mathbf{11}}\mathit{N}{\mathit{m}}^{\mathbf{2}}\mathit{k}{\mathit{g}}^{\mathbf{-}\mathbf{2}}\mathbf{.}$.
2. The gravitational force between two objects having mass M and m respectively at distance ‘d’ is given by:

$$\begin{gathered} F=\frac{GMm}{d^2} \\ \Rightarrow G=\frac{F{d}^2}{Mm} \end{gathered}$$
