- Homework Statement
- The angle between two vectors a and b (along the adjacent sides of a parallelogram) is an acute angle. The vector a-b will be (a)major diagonal of parallelogram (b)minor diagonal of parallelogram (c)none
- Relevant Equations
- Vector diagram
We know that the sum of the two vectors is represented by the major diagonal.
Now, if I draw the vector diagram, it turns out to be a diagonal of an entirely different parallelogram. So, my first answer was (c) none.
But, I noticed that when parallelly shifted, it turns out to be the minor diagonal of the above parallelogram. So, I switched to (b).
But the correct answer according to my book is (a).
Can anyone explain this?
