Wood reacts with the oxygen in air and burns. But a pile of wood sitting next to a fireplace doesn't randomly start burning. You have to start the fire. Why do you think this is the case?

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
