Solution

The correct option is B $\frac{426^i - 897^j + 9654^k}{489}$
Vector component of $\to a$ perpendicular to $\to b = \to a - \frac{(\to a . \to b)}{| \to b |^{2}} \to b$
Thus, here, $(2^i + 23^j + 22^k) - \frac{552}{489} (^i + 22^j + 2^k) = \frac{426^i - 897^j + 9654^k}{489}$

Let →a=2^i+23^j+22^k and →b=^i+22^j+2^k. The vector component of →a perpendicular to the direction of →b is

The correct option is B 426^i−897^j+9654^k489Vector component of →a perpendicular to →b=→a−(→a.→b)|→b|2→bThus, here, (2^i+23^j+22^k)−552489(^i+22^j+2^k)=426^i−897^j+9654^k489

Let $\to a = 2^i + 23^j + 22^k$ and $\to b =^i + 22^j + 2^k .$ The vector component of $\to a$ perpendicular to the direction of $\to b$ is

The correct option is B $\frac{426^i - 897^j + 9654^k}{489}$
Vector component of $\to a$ perpendicular to $\to b = \to a - \frac{(\to a . \to b)}{| \to b |^{2}} \to b$
Thus, here, $(2^i + 23^j + 22^k) - \frac{552}{489} (^i + 22^j + 2^k) = \frac{426^i - 897^j + 9654^k}{489}$
