the summation of two unit vectors is a third unit vector then the modulus of the difference of these unit vectors is

a+b=c ...... (i) and |a|=|b|=|c|=1


Now, magnitude of sum of a and b is

|a+b|=|a|^2+|b|^2+2(a⋅b)

1=1+1+2(a⋅b) ..... From (i)

a⋅b=−1/2


Magnitude of their difference is given by

|a−b|^2=|a|^2+|b|^2−2a.b

=1+1+2×21=3

|a−b|=root (3)
