For a science experiment, Lorraine is testing a cloth that is electrically charged and an uncharged cloth to see if they will attract an uncharged object. Which cloth is the control in her experiment? The charged cloth
The uncharged cloth
The uncharged object
Both cloths

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
