Question

The value of the universal gravitational constant

• A. changes with change of place
• B. does not change with place to place
• C. becomes more at night
• D. becomes more during day

Answer 1

The correct option is B

does not change with place to place

1. Gravitational force between two masses $m_1\text{and}{m}_2$ at the distance of $R$ is given by $F=\frac{G{m}_1{m}_2}{R^2}$where

$$\begin{gathered} F\text{is gravitational force.} \\ R\text{is radius.} \\ G\text{is the gravitational constant.} \end{gathered}$$

2. $G$ is a gravitational universal constant that does not change from place to place.

Hence, option (b) is correct.
