For component of a vector 
, match the following columns.
Column I | Column (I | ||
(A) | -axis | (I) | unit |
(B) | Along another vector | (II) | 3 unit |
(C) | Along | (III) | Zero |
(D) | Along another vector | (IV) | unit |
Choose the correct answer from the options given below
Text Solution
Verified by ExpertsA
is perpendicular to 
, because the 
product of these two vectors is zero.
Further 
vector is parallel to A. So, component of 
along this vector is magnitude of 
which is 
unit.
The last vector i.e. 
is anti-parallel to 
along this vector is negative of magnitude of 
of 
unit.
