Question

A feather of mass 20g is dropped from a height. It is found to fall down with a constant velocity. What is the net force acting on it?

Answer 1

Answer:

The net force acting on it is 19.6\times10^{-2}\ N19.6×10

−2

N

Explanation:

Given that,

Mass = 20 g

When a feather is dropped from a height with a constant velocity it means the acceleration is zero.

So, The net force acting on the feather

F = mg+maF=mg+ma

F = 20\times10^{-3}\times9.8+0F=20×10

−3

×9.8+0

F = 0.196\ NF=0.196 N

F = 196\times10^{-3}\ NF=196×10

−3

N

Hence, The net force acting on it is 19.6\times10^{-2}\ N19.6×10

−2

N
