Question

Pluto has a radius of 1.15 x 106 m
and a mass of 1.31 x 1022 kg.
What is the acceleration of gravity on
its surface?

Answer 1

Answer:

$g=0.66\ m/s^2$

Explanation:

We have,

The radius of Pluto is $1.15\times 10^6\ m$

Mass of Pluto is $1.31\times 10^{22}\ kg$

It is required to find the acceleration of gravity on  its surface. The formula used to find the acceleration is given by :

$g=\dfrac{Gm}{r^2}\\\\g=\dfrac{6.67\times 10^{-11}\times 1.31\times 10^{22}}{(1.15\times 10^6)^2}\\\\g=0.66\ m/s^2$

So, the acceleration due to gravity on Pluto is $0.66\ m/s^2$.
