Figure shows the orientation of two vectors u and v in the xy-plane:
If 
and 
A
a and p are positive while b and q are negative
B
a, p and b are positive while q is negative
C
a, q and b are positive while p is negative
D
and q are all positive
Text Solution
Verified by ExpertsThe correct answer is:
B
Clearly from the diagram, 
As 
is in the first quadrant. Hence both components a and 
will be positive.
For 
as it is in positive 
-direction and located downward hence 
-component 
will be positive and 
-component 
will be negative.
