Figure shows the orientation of two vectors `u` and `v` in the `XY` plane.
if `vecu=ahati+bhatj` and `vecv=p hati+qhatj`
which of the following is correct?

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

a, b, p and q are all positive.

Text Solution

Verified by Experts

The correct Answer is:
B
As per figure , in `vecu = a hati + b hatj,` both a and b are positive while in `vecv = p hati + q hatj` , p is positive and q is negative . Thus a, b and p are positive and q is negative.
