0.29 mol of argon gas is admitted to an evacuated 50 cm3 container at 20∘C. The gas then undergoes an isochoric heating to a temperature of 200 ∘C. What is the final pressure of the gas in pascals?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
