What is the dot product of vectors i and j?

A. 0

Step 1: Identify the concept: this is dot product of unit vectors. Step 2: i and j are perpendicular unit vectors so their dot product is 0. Step 3: Remember different perpendicular unit vectors have dot zero.

Step 1: concept पहचानें: यह unit vectors का dot product है। Step 2: i और j perpendicular unit vectors हैं इसलिए उनका dot product 0 होता है। Step 3: Different perpendicular unit vectors dot zero याद रखें।
