(b) Use the right-hand rule to decide whether the components of a × b are positive, negative, or 0.

Gekata [30.6K]

(a)

Given:

$\vec{a}$ is in xy plane and $\vec{b}$ is in the direction of k.

|a|=6 units, |b|=3 and θ = 90°

|a × b| = |a| × |b| sinθ

= |a| × |b| sin90°

= 6 × 3 × 1

|a × b| = 18

(b)

Let $\vec{c}=\vec{a} \times \vec{b}$

$\vec{c}$ is perpendicular to both $\vec{a} \text { and } \vec{b}$ .

In this case,

x-component of $\vec{a} \times \vec{b}$ is positive.

y-component of $\vec{a} \times \vec{b}$ is negative.

z-component of $\vec{a} \times \vec{b}$ is zero.
