Question

vi)
*
If A.B = 0 and Āx B = 0 and A is not =0 then the vector B is
*Equal to A
* perpendicular to A
* parallel to A
*Zero​

Answer 1

Answer:

Zero

Explanation:

We can see $ABcosx = 0 => cos x = 0 => x=90$

Also

$ABsinx = 0 => sin x= 0=> x= 0$

Thus, we can see that for no angle is sin and cos both zero. Therefore, the magnitude of one of the vectors should be 0. Since, it is given A is not equal to 0. It is quite evident that B vector magnitude should be zero.
