17. A vector A points vertically upward and B points
towards north. The vector product Ax B is :-(1) null vector
(2) along west
(3) along east
(4) vertically downward
1. Null vector or zero
Lets A, B & n as vectors.
A is pointing upwards. B is pointing north, which is also upwards.
Vector product is given by:-
A x B = |A| |B|Sin θ x n
where n is a vector perpendicular in the direction of both A & B.
Angle θ between A & B is zero, as A & B both are parallel to each other.
A x B = |A| |B|Sin 0 = 0
Hence vector product of vector A & vector B is zero.
U can use the right hand thumb rule to do it.Draw the vectors or u may hv to imagine little straighten ur palm n place it on the the first vector in the cross product i.e. A now roll ur fingers towards the B vector, the dirction in which ur thumb is pointing will the the direction of the cross product vector.its kind of messy answer so check in u tube once the right hand thumb rule n apply it as i tld.
right hand palm rule
please mark my answer as brainliest
And is d
equal to zero
angle between them is 0°
ANGLE BETWEEN A AND B IS 90°
It'ssuch like that take a pen pointing towards you and take another pen towards north then the resultant will be in west if you observe it
its is towards west my dear friend
see the photo hope you will be able to understand.
the class is not in a good position for a good reason for a job or I am a bit more than a bit more of an engineer and a good manager of a different business than I have ever had doubt about your business as a business owner of the best of the kind that simple business can be and the best
towards north. the vector product ax b is...
