When two vectors are perpendicular their dot product is


Open in App
Solution

Step 1. Given data:

Assume two vectors AandB.

Step 2. Formula used:

A.B=ABcosθ

Step 3. Applying the concept:

When two vectors are perpendicular, it means that the angle will be 90

The dot product of two vectors is given by,

A.B=|A||B|cos90A.B=|A||B|(0)A.B=0

Thus, the dot product of two vectors when they are perpendicular is zero.
