The force exerted on the bottle is 532 N
Explanation:
When the air is removed from inside the bottle, vacuum is created, therefore the external pressure (the atmospheric pressure) is no longer balanced, and it creates a net force downward on the can.
The pressure is related to the force by the equation:
where
p is the pressure
F is the force
A is the area of the can
Here we have:
is the atmospheric pressure
r = 0.0410 m is the radius of the can, so the area is
And solving for F, we can find the force on the can:
