The mass of an imaginary planet is 3 times the mass of the earth. Its diameter 25600 km and the earth's diameter is 12800 km. Find the acceleration due to gravity at the surface of the planet. [g (earth) `=9.8m//s^(2)`]

Explanation

To find the acceleration due to gravity at the surface of the imaginary planet, we can use the formula for gravitational acceleration:

\[ g = \frac{GM}{R^2} \]

Where:
- \( g \) is the acceleration due to gravity,
...
