Question

The magnitude of vector product of two
unit vectors making an angle of 60° with
each other is
(A) 1
(B) 2
(C) 3/2
(D) 1312​

Answer 1

Answer:root(3)

Explanation:

Resultent is given by

Root(Asquare +Bsquare +2ABcos@)

Unit vector is a vector having magnitude =1

So

Applying in equation

Root{(1*1)+(1*1)+2(1)*(1)*(1/2)}... cos60is 1/2

Solving ans root(3)
