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:

if c = axb

c = absinθ

a = b = 1 (unit vectors )

sin60° = √3/2

c = 1*1*√3/2 = √3/2

option (D) √3/2

Answer 2

Answer:

√3/2

Explanation:

Let unit vectors be A vector and B vector.

magnitude of vector products will be ABsin(60).

|A|=|B|= 1 , they are unit vectors.

sin(60)= √3/2

hense ans will be √3/2
