Question

What is the net force on an object with an air resistance of 250 N and gravity applying 500 N?1 0 N2 750 N4 250 N Upward5 250 N downward

Answer 1

Given,

The air resistance on the object, f=250 N

The gravitational force, F=500 N

The gravitational force pulls an object downwards, towards the center of the earth. Air resistance is the resistive force that opposes the downward motion of the object.

As the downward gravitational force is greater than the upward resistive force, the net force will be directed downward.

Thus, the net vertical force on the object is given by,

`F_n=F-f`

On substituting the known values,

`\begin{gathered} F_n=500-250 \\ =250\text{ N} \end{gathered}`

Therefore, the net force on the object is 250 N downward.
