Question

Fig. 3.1 shows an oil can containing only air at atmospheric pressure.
Atmospheric pressure is 1.0 × 10⁵ Pa.
The pressure of the air in the can is reduced by means of a pump. The can collapse when the pressure of the air in the can falls to 6000 Pa.

i) Explain why the can collapse
ii) The surface area of face X of the can is 0.12m².
Calculate the resultant force on face X when the can collapses.

Answer 1

Answer:

out side pressure is more than inside
