Answer:

Given:

2 vectors are provided:

  • 2i + 5j + nk
  • 2i - j + k

To find:

Value of "n" for which the vectors are perpendicular to each other.

Concept:

Always remember the fact that for any perpendicular vectors, the dot product (scalar product) is zero.

Calculation:

A . B = 0

=> (2i + 5j + nk)(2i - j + k) = 0

=> 4 - 5 + n = 0

=> n - 1 = 0

=> n = 1

So the value of n = 1.
