Thanks for the response.
But what if the two vectors are of different magnitude and are anti parallel.
Then infact we'll have to subtract their magnitudes that will be |A-B| , but what if we want to write them in vector form, what would we write them if we want to get resultant?
Some people told me that as they are anti-parallel, then their resultant will be ultimately
One of my friend argued that the resultant should be A+B because
Let two vectors [b]A[/b] and [b]B[/b],
[b]A[/b]= |A| ([i]k[/i] )
[b]B[/b]= |B| (-[i]k[/i])
[b]A[/b] + ([b]-B[/b])
[|A| (k)] + [|B| (-k)]
As |B|(-k)= [b]B[/b]
[b]A[/b] + [b]B[/b]
Now if it is A+B, then it means that they would be added to each other, and their magnitutude should also be added?
Please do try to understand what I've written, and help me.
Waiting for the reply
