A handbag weighing 162 N is carried by two students each holding the handle of the bag next to him. If each handle is inclined at 60° to the vertical, find the force on each
student's arm?

162 N

Explanation:

Since the handbag weighs 162 N, from Newton's third law of motion, we know that to every action, there is an equal and opposite reaction. Thus, it means the force by each student arms Carrying the bag will be 162 N.

Since both handles of the bag are at same inclined angle of 60°, then the force in each students arm will be equal and thus;

F_each arm = 162 N
