Question

two equal vector have a resultant equal to either of the two .The angle between them is​

Answer 1

Answer:

what is vector. I do t understand

Answer 2

Answer:

Let 2 equal vectors be A

by using formula

√A^2+B^2-2ABcosx= R

Here A=B=R ,x is angle between them

so,

√A^2+A^2-2A^2cosx=A

A√2-2cosx=A

√2-2cosx=1
