Question

State & explain the factors upon which value of ‘g’ at a place depends.

Answer 1

1. The acceleration due to gravity at any place can be expressed by:

$$\begin{gathered} g=\frac{G\times M}{R^2} \\ where, \\ g\to accelerationduetogravity \\ G\to UniversalGravitationalcons\tan t \\ M\to MassoftheEarth \\ R\to Height\left(altitude\right)ofthatplace \end{gathered}$$

2. Thus, the acceleration due to gravity depends only on the height of that place from the centre of the Earth.
