What is the scalar projection of a=(6, 4, 0) on b=(1, 0, 0)?
a=(6, 4, 0) का b=(1, 0, 0) पर scalar projection क्या है?
Show answer and explanation
Correct Answer
D. 6
ExplanationStep 1: Identify the concept: scalar projection. Step 2: Scalar projection=(a·b)/|b|. Here a·b=6 and |b|=1, so answer is 6. Step 3: Exam tip: The denominator in projection is the magnitude of the vector projected onto.
Step 1: अवधारणा scalar projection है। Step 2: Scalar projection=(a·b)/|b| है। यहाँ a·b=6 और |b|=1, इसलिए 6। Step 3: याद रखें: Projection में denominator projection वाले vector की magnitude है।
