JEE Main 2022 · 26 Jul · Shift 2, Physics question 51

If A⃗=(2i^+3j^−k^)\vec A=\left(2\hat i+3\hat j-\hat k\right) m and B⃗=(i^+2j^+2k^)\vec B=\left(\hat i+2\hat j+2\hat k\right) m. The magnitude of component of vector A⃗\vec A along vector B⃗\vec B will be ______ m.

Answer and worked solution

Official answer: 2

Component A⃗⋅B⃗∣B⃗∣=2+6−23=2\frac{\vec A\cdot\vec B}{|\vec B|}=\frac{2+6-2}3=2 m.
