A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Any vector 
in plane of 
must be in form of linear combination of 
and 
Such combination is possible in alternate 
As 
…..(i)
Also (i) is perpendicular to 
As 
Thus unit vector perpendicular to 
and coplanar with 
is, 
.
