Given :
- A planet's mass is thrice as that of earth.
- And, radius is twice as that of earth.
To find :
- Value of g on the surface of planet.
___________________________________________
If Earth's mass is m and its radius is r. So, acceleration due to gravity on its surface is given by,
- G denotes acceleration due to gravity
- m denotes mass
- r denotes radius
Now, as the planet's mass is thrice as that of earth and radius is twice as that of earth. So,
- Planet's mass = 3m
- Planet's radius = 2r
Now, acceleration due to gravity on the surface of the planet will be given by,
Therefore, the value of g on the surface of planet ¾th of the value of g on the earth
