Question

if A = 6i + j -2k and B = 4i ,AB gives

Answer 1

Answer:

A=6i+j-2k, B=4i

AB =24i²+4ij-8ik

Answer 2

Concept:

Vectors are the quantities that have a direction and a magnitude. It cannot be expressed by a single number. It can be of many types for example unit vector, zero vector, position vector, negative vector, etc. Vectors represent the two and three dimensional lines which have a magnitude and a direction. It can be represented in a 2D or a 3D plane.

Given:

We are given:

A = 6i + j -2k and B = 4i

Find:

We need to find AB.

Solution:

We know that:

AB=B-A

Substituting the values of A and B, we get:

AB= (4i)-(6i + j -2k)

Simplifying the expression, we get:

AB=4i-6i-j+2k

AB=-2i-j+2k

Therefore, the value of AB will be -2i-j+2k.
