Riddle073:
your case is about the equal matnitude of vectors i and j
what if i>j or j>i these are the cases bro
i is greater than j and i is less than j are two cases
you are dealing with i is equal to j
i is greater than j and i is less than j are two cases
i is greater than j and i is less than j are two cases
i is greater than j and i is less than j are two cases
what about other two cases?
the correct answer is 0 to 180 degree
Sorry Your answer is the correct one

Both the vectors are inclined at 45' with the x axis in opposite directions so 45 + 45 = 90 hence the angle between them is 90 degree.
Hope ot helps :)

It is not always 45 degree
We have to relate with all possibilities
The answer is 0 to 180 degree
But dear,
The vectors we are given are not variables they are constant so there would be the exact same direction
Oh yes
