First of all the basic concept which everyone makes wrong is that Subtraction of vector,which really doesn't exist

>>Vectors can only be add.

>>Negative vector means ; Motion in opposite directions

Learn this formula :

yashkumar44: Answer is 5 * -1 * i^

yashkumar44: -5^i

yashkumar44: since cos 180°=-1

yashkumar44: hope u understood

ashraytiwari17: i have not studied those with magnitude yet

yashkumar44: ok ok

ashraytiwari17: i will see yr comment again after studying

yashkumar44: but remember that it depends on cos theta

ashraytiwari17: ok

ashraytiwari17: okthncz

it's just like normal sub

example..(a vector -2b vector) -(2a vector- 3b vector)

answer: -a vector+b vector

hope it helps

ashraytiwari17: is the angle that we take between two vectors always acute?

ashraytiwari17: when i say always, i mean it. ALWAYS?

queen1229: sorry ur question is from Physics but i thought it is from maths
