What will be the relation between the acceleration due to gravity on the surface of the earth and on a planet respectively, whose mass and radius are four times that of the earth ?

Explanation

To find the relation between the acceleration due to gravity on the surface of the Earth and on a planet whose mass and radius are four times that of the Earth, we can follow these steps:

### Step 1: Understand the formula for acceleration due to gravity
The acceleration due to gravity \( g \) at the surface of a planet is given by the formula:
\[ g = \frac{G \cdot M}{R^2} \]
where:
