Question

08. Two vectors A and B are at right angles to each other.
when
(a) AxB = 0 (b) A.B =0
(C) A = B (d) A.B = A XB​

Answer 1

Answer:

If angle is 90 degree then their dot product is 0 .

I.e A.B = abcos x where x is the angle

= abcos 90

= 0

Answer 2

Answer:

a) A.B=0, where Force=A and Displacement=B

Explanation:

Heya Mate..

We know that, Work Done= Force.Displacement

W=F.S

So, A.B=0.
