A box-shaped metal can has dimensions 8 in. by 4 in. by 10 in. high. All of the air inside the can is removed with a vacuum pump. Assuming normal atmospheric pressure outside the can, find the total force on one of the 8-by-10-in. sides

Answer:

The force on the side is 5252 N.

Explanation:

Area, A =  8 in x 10 in = 80 in^2 = 0.052 m^2

height, h = 10 in

The force on the area is

F = P x A

where, P is the atmospheric pressure and A is the area.  

P = 1.01 x 10^5 Pa

Force = 1.01 x10^5 x 0.052 = 5252 N
