What is the scalar projection of vector a=(7,1,3) on vector b=(1,2,2)?
Vector a=(7,1,3) की vector b=(1,2,2) पर scalar projection क्या है?
Show answer and explanation
Correct Answer
A. 5
ExplanationStep 1: scalar projection is a·b/|b|. Step 2: a·b=15 and |b|=3, so the projection is 5. Step 3: tip: scalar projection uses |b| in the denominator, not |b|^2.
Step 1: scalar projection = a·b/|b| है। Step 2: a·b=15 और |b|=3, इसलिए projection 5 है। Step 3: tip: projection में denominator |b| होता है, |b|^2 नहीं।
