Question

A feather of mass 10g is dropped from a height. It falls with a constant velocity. What is the net force acting on it?

Answer 1

In this case, the net force acting on the feather is zero.

The reason behind is that two forces, i.e. the gravitational force (pulling the feather downwards) and the air-drag force (working in the upward direction), both cancels out each other.

Hence, net force is zero.

Answer 2

Answer:

The net force acting on is zero.

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

Hence, The net force acting on it is
