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

Explanation

To solve the problem of finding the relation between the acceleration due to gravity on the surface of the Earth and on a planet whose mass and radius are both twice 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:
