The vector sum of two vectors 
and 
is maximum, then the angle 
between two vectors is -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For two vectors A and B , the magnitude of their resultant is
Using the formula, 
where 
is the angle between the vectors.
For R to be maximum, the term 
must be maximum.
Since the maximum value of 
is 1
Therefore, the vector sum is maximum when the two vectors are in the same direction.
