Vedclass · Answer

(D) The dot product of two vectors $\vec{A}$ and $\vec{B}$ is defined as $\vec{A} \cdot \vec{B} = |\vec{A}| |\vec{B}| \cos 	heta$,where $	heta$ is the angle between the vectors.If the vectors are at right angles,then $	heta = 90^\circ$.Substituting this into the formula,we get $\vec{A} \cdot \vec{B} = |\vec{A}| |\vec{B}| \cos 90^\circ$.Since $\cos 90^\circ = 0$,the dot product $\vec{A} \cdot \vec{B} = 0$.
