Vector has a magnitude of 130 units and points 31.0 ° north of west. vector points 66.0 ° east of north. vector points 14.0 ° west of south. these three vectors add to give a resultant vector that is zero. using components, find the magnitudes of (a) vector and (b) vector .

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
