Question

Calculate the gravitational force of a 90.0 kg person who is standing on the planet next to your name . Write the given , equation , substitution , and final answer in 3 significant figures . lanet Mass (kilograms ) Radius( meters Mercury 3.29 9 * 10 ^ 23 2.44 x 10 ^ 6 Planetary Data

Answer 1

this is the mass of the person.

Force of gravitation is given by,

`F=\frac{\text{GmM}}{r^2}`

M is the mass of the planet.

G is the universal gravitational constant. r is the radius of the planet.

substituting the values we get,

`\begin{gathered} F=(6.67*10^(-11)*3.29*10^(23)*90.0)/((2.44*10^6)^2) \\ =331.7\text{ N} \end{gathered}`

hence the gravitational force is 331.7N
