WebIf the pressure of a gas becomes 5 times its original pressure, then the density of the gas changes from d gm/lit to____ gm/lit. View Solution play_arrow Download Complete Course WebStep 1: Given data Force ( F) = 50N Area ( A) = 10m2 Step 2: Calculation of the pressure developed: Pressure is defined as the force per unit area. That is, P ressure(P) = F orce(F) Area(A) Putting all the values, we get P = 50N 10m2 P = 5N m−2 P = 5P a Hence, the pressure developed is 5P a . Thus, Option B) 5P a is the correct option.
