    Any physics people able to answer this? Have done it myself but the markscheme says it is wrong but I can’t see how their answer can be right. Any anwers welcome.

    When flyingm the pressure inside the cabin of an aircraft is 70 kPa. The aircraft window has an area of 810 cm^2. The aircraft is flying at 12Km, with an atmospheric pressure of 20 kPa. What is the resultant force acting on the aircraft window?

    Many thanks

    DId you take into account the pressure's as 70,000 Pa and 20,000 Pa, as well as the area being 810 x 10^-2 m^2??

    Yes, did the covereions, used p=f/a and then subtracted the forces. Their answer seemed ridiculous.
