Planet x has a mass 7.27 times that of the
earth and a radius 4.13 times the radius of
the earth.
what is the acceleration due to gravity on
the surface of planet x, measured in units of g
(the gravitational acceleration on the surface
of the earth)?

0.426g

Explanation:

Since the gravitational acceleration on a planet is in the following formula:

where G is the gravitational constant, M is the planet mass and R is the planet radius.

So if Planet X has a mass 7.27 times that of Earth and radius of 4.13 that of Earth, the ratio in gravitational acceleration g shall be

that would be because of both gravity and friction. so     c
