In a classroom demonstration, the pressure inside a can is suddenly reduced to essentially zero. Assuming the can to be a cylinder with a height of 13 cm and a diameter of 43 cm, find the net inward force exerted on the vertical sides of the can due to atmospheric pressure.
The Surface Area of the cylinder is: 2pie(r^2)+2pie(r)(h).
The astmospheric pressure is: 1.01E5 Pa.
Should I just be using the P=F/A, P(A)=F?

Given the the energy of the atmospherr per unit volume the total force or weight of the atmosphere on the earth can be calculated.
In the case of a cylinder metal can the pressure on the surface of the can timesthe total surface would give you the force on the can. the can may not collapse if the steel structure is resitive enough even though the inside pressure is zero.
