Question

If Á = 2i – 3j and B = 21 – 5j, calculate the direction of A - B​

Answer 1

Given,

Two vectors A = 2i – 3j and B = 2i – 5j.

To Find,

The direction of vector A-B.

Solution,

To Find the vector A-B, we need to subtract the vector B from vector A.

A-B = 2i-3j-(2i-5j)

      = 2i-3j-2i+5j

      = 2j.

Hence, the direction of A-B is 2j.

Answer 2

Answer:

Calculate the direction.

Explanation:

Given:

$A= 2i - 3j$

$B= 2i -5j$

Calculation:

$A-B= 2i-3j-(2i-5j)\\ =2i-3j-2i+5j\\ = 2j$

Hence, the direction is along positive side.$2j$
