Q11 of 61 Page 318

The acceleration due to gravity on the surface of a planet whose mass and radius are both one-third of the Earth (acceleration due to gravity on the earth is g):

We know that, where M is mass of earth and R is radius of earth.


Now, from the question,


M’ =


R’ =


So, the g’ will be:






Hence, option B is correct.
