When two vectors `vecA` and `vecB` of magnitudes `a` and `b` respectively are added, the magnitude of resultant vector is always

When two vector vec a and vec b are added,the magnitude of the resultant vector is always

Two vectors have magnitudes 6 and 8 units, respectively. Find the magnitude of the resultant vector if the angle between vectors is (a) 60^(@) (b) 90^(@) and ( c ) 120^(@) .

There are two vectors of equal magnitudes. When these vectors are added, then magnitude of the resultant is also equal to the magnitude of each of the two given vectors. Angle between the vectors is

The maximum and minimum magnitude of the resultant of two vectors are 17 units and 7 units respectively. Then the magnitude of the resultant of the vectors when they act perpendicular to each other is :
