Question

Calculate the gravitational force of a 90.0 kgperson who is standing on the planet next toyour name. Write the given, equation,substitution, and final answer in 3 significantfigures into your notebook.PlanetaryDataPlanetMass (kilograms) Radius(meters)6.39 x 10233.39 x 106Mars

Answer 1

Given data:

Mass of the person;

`m=90.0\text{ kg}`

Mass of the planet;

`M=6.39*10^(23)\text{ kg}`

Radius of the planet;

`r=3.39*10^6\text{ m}`

The gravitational force is given as,

`F=(GMm)/(r^2)`

Here, is universal gravitational constant.

Substituting all known values,

`\begin{gathered} F=(6.67*10^(-11)*6.39*10^(23)*90)/((3.39*10^6)^2) \\ =333.787\text{ N} \end{gathered}`

Therefore, the gravitational force experinced by the person is 333.787 N.
