Question

iv) 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) 13/2​

Answer 1

Answer:  $\sqrt{3}/2$

Explanation:

1. Given , ∅=60°

• Let the tow unit vector a and b

• and their magnitude are |a| & |b| respectively.

• ∴ their vector product will be

                  a×b= |a|.|b|.sin∅

                        =   1 .  1 .sin60°

                        =    √3/2

                                        Answer.
