In the given figure, particle is in equilibrium under the effect of the forces shown which are in newtons. Find the force .
A body weighing 12 N is attached to one end of a light, inextensible string. The other end of the string is fixed to a vertical wall. A horizontal force , holds the body in equilibrium when the measure of the angle between the wall and the string is . Find , the tension in the string and , the horizontal force.
A body weighing N is placed on a smooth plane inclined at to the horizontal. If it is kept in equilibrium under the action of a horizontal force of magnitude 33 N, find the weight of the body and the reaction of the plane .
