CBSEENPH11017953

If magnitude of two vectors is 5 and 2 units respectively, then what can be the maximum possible magnitude of the resultant of these two vectors?

Solution
Given, 
Magnitude of first vector = 5
Magnitude of second vector = 2
Resultant of two vectors = square root of 5 squared plus 2 squared end root  
Therefore, the maximum possible magnitude of the resultant of the two vectors is 7 units.
