Question

If the sum of two unit vectors is unit vector then the magnitude of their difference is
a) √2
b) √3
c)1/√2
d) √5​

Answer 1

 the sum of two unit vectors is a unit vector,then find themagnitude of their differences. →ns=→n1+ˆn2. Since it is given that →ns is a unit vector, so ns=1

Answer 2

Answer:

So the answer is.....

√5
