Question

What is the net force acting on a leaf of mass 2 g falling from a tree with a constant velocity?

• A. 0.2 N
• B. 2 N
• C. 20 N
• D. 0 N

Answer 1

The correct option is D 0 N

We know that
$Force=\frac{\Delta p}{\Delta t}$ = $ma$
Since, leaf is falling with constant velocity.
$\Rightarrow$ $a=0m{s}^{-1}$
$\Rightarrow$ $F=0N$
