Let 
, 
and 
be three vectors such that the projection vector of 
on 
is 
.
If 
is perpendicular to 
, that 
is equal to :
A
B
6
C
D
4
Text Solution
Verified by ExpertsThe correct answer is:
B
Projection of 
on 
According to question 
= 
= 2
⇒ 
…(1)
Since, 
is perpendicular to 
.
Hence, 
⇒ 8+5 
…(2)
From (1) and (2)
