Question

The sum of two unit vectors is also a vector of unit magnitude, then the magnitude

of the difference of the two unit vectors is

1) 1 unit 2) 2 units 3) 3 units 4) zero
​

Answer 1

Answer:

Let us assume that the difference of unit vectors →a and →bis a vector |→d|. Hence the magnitude of difference of two unit vectors is √3. So, the correct answer is “Option 3"
