The acceleration of gravity on the surface of planet X is 2.95 times the acceleration of gravity on the surface of Earth and the radius of planet X is 3.5 times the radius of Earth. What is the mass of planet X?

The mass of planet X is 36.23 times that if earth.                                  

Explanation:

Given that,

The acceleration of gravity on the surface of planet X is 2.95 times the acceleration of gravity on the surface of Earth and the radius of planet X is 3.5 times the radius of Earth

The formula of acceleration due to gravity is given by :

G is universal gravitational constant

M is mass of Earth and r is radius of Earth

Let is the acceleration due to gravity on the surface of planet X. So,

 .......(1)

M' is the mass of planet X and r' is the radius of planet X.

So,

 .....(2)

Dividing equation (1) and (2) we get :

So, the mass of planet X is 36.23 times that if earth.
