If A → = 2 i ^ + 3 j ^ - k ^ m and B → = i ^ + 2 j ^ + 2 k ^ m . The magnitude of component of vector A → along vector B → will be _____ m .

Correct answer

0

Step-by-step solution

GIven vector are A → = 2 i ^ + 3 j ^ - k ^   m and B → = i ^ + 2 j ^ + 2 k ^   m Component of A → along B → = A → · B ^ = A → · B → B → = 2 + 6 - 2 1 2 + 2 2 + 2 2 = 6 3 = 2
