Question

(ix) If a and b are two collinear vectors then axb
equal to :
(a) 1

(b) ab
(c) 0
(d) Not defined​

Answer 1

ANSWER = (D) Not defined ...........

Answer 2

Answer:

c is the right answer.

Step-by-step explanation:

Collinear mean passing through same points so there angle is 0 so cross product is zero.

a×b=absin theta n'

a×b=ab sin (0) n'

a×b=ab(0)n'

a×b=0 I hope it will help you.
