Aconstant force is applied to an object, causing the object to accelerate at 10 m/s^2. what will the acceleration be if the force is halved and the object's mass is doubled?

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
