Question

Find the scaler component of a unit vector which is perpendicular to vectors i+2j-k and 3i-j+2k.

Answer 1

3i 5j 7k

Step-by-step explanation:

Let the vector perpendicular to the vectors i+2j-k and 3i-j+2k is xi + yi + zk

If two vectors are perpendicular than their dot product is zero.

Find dot product

x + 2y = z = 0

3x − y + 2z = 0
