What is the vector projection of a=(2,3,6) on b=(1,2,2)?
a=(2,3,6) का b=(1,2,2) पर vector projection क्या है?
Show answer and explanation
Correct Answer
A. (20 / 9)(1,2,2)
ExplanationStep 1: Identify vector projection. Step 2: Vector projection=(a·b/|b|²)b; here a·b=20 and |b|²=9, so it is (20/9)b. Step 3: Exam tip: Vector projection uses |b|² in the denominator.
Step 1: अवधारणा vector projection है। Step 2: vector projection=(a·b/|b|²)b, यहां a·b=20 और |b|²=9 है, इसलिए (20/9)b। Step 3: Exam note: vector projection में denominator |b|² होता है।
