Two forces of magnitudes 3 units and 5 units act at `60^(@)` with each other. What is the magnitude of their resultant ?

When two right angled vectors of magni-tude 7 units and 24 units combine, what is the magnitude of their resultant ?

Two equal forces of magnitude 'p' each are angled first at 60° later at 120°. The ratio of magnitude of their resultants is

An ant moves on the floor of a room making two displacement. One of magnitude 3m and another of magnitude 4m. If the angle between the two displacements is 120^(@) what will be the magnitude of the resultant displacement ?
