Question

A 50- kilogram student stands on the surface of the earth. what is the magnitude of the gravitational force of the eart

Answer 1

490 N

Step-by-step explanation:

The magnitude of the gravitational force acting on an object on the surface of the Earth is given by:

`F=mg`

where

m is the mass of the object

g = 9.8 m/s^2 is the acceleration due to gravity

In this problem, we have a student with mass m=50 kg, so the force of gravity in this case is

`F=(50 kg)(9.8 m/s^2)=490 N`
