If A → = 2 i ^ + 3 j ^ - k ^   m and B → = i ^ + 2 j ^ + 2 k ^   m . The magnitude of…

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

Solution

GIven vector are A→=2i^+3j^-k^ m and B→=i^+2j^+2k^ m

Component of A→ along B→=A→·B^

=A→·B→B→=2+6-212+22+22=63=2
