For component of a vector A=(3hati+4hatj...

For component of a vector `A=(3hati+4hatj-5hatk)`, match the following table

Text Solution

Verified by Experts

The correct Answer is:
A`to`q, B`to`r , C`to` s, D`to`s
`(2hati+hatj+2hatk)` is perpendivular to A because the dot product of these two c vector is zero .
Futher `(5hati+8hatj-10hatk)` vecto0r is parallel to A , so component of A along this vector si magnitude os A which is `5sqrt(2)` unit the last vector i.e `(-3hati-4hatj+5hatjk) ` is anti -parallel to A along this vector is nagative of magnitude of magnitude opd A or `-5sqrt(2)` unit
