Question

the area of a book cover is 0.025 m square and the pressure exerted by the air is 5000pascals . what force will be exert on the book when it is placed on a desk

Answer 1

Heya........!!!

____________________________

Given in the question :-

•--» Area ( A ) = 0.025 m^2

•--» Pressure ( P ) = 5000 pascal

By applying the formulae : P = F / A we can take out the value of force ( F ) .

=> P = F/A
=> F = PA

=> Force = 5000 × 0.025

♦ Force exerted => 125 N
