Question

The sum of two unit vectors is √3 units then difference between is​

Answer 1

Answer:

sum of unit vectors=

root a² +b²+2abcos@

root3=root(1²+1²+1)

therefore

2ab cos @ has to be 1

hence cos@=1/2

Explanation:

difference=roota²+b²-2abcos@

=root1²+1²-1

=1

Hence the answer is 1 unit
