NCERT · Class 11 · Physics · Motion in a PlaneWhat is the direction of the cross product of two vectors $\vec{A}$ and $\vec{B}$ lying in the plane of the paper?
Step-by-Step Solution
According to the right-hand rule, the cross product vector $\vec{A} \times \vec{B}$ is perpendicular to the plane containing both vectors $\vec{A}$ and $\vec{B}$, which means it is directed normally outward or inward relative to the paper.
