The density of a planet is doubled without changing its radius. How wil it effect the acceleration due to gravity in the planet?

Explanation

To solve the problem of how doubling the density of a planet affects its acceleration due to gravity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Acceleration Due to Gravity (g):**
The acceleration due to gravity at the surface of a planet is given by the formula:
\[
g = \frac{GM}{R^2}
