This question aims to find the $2$ vectors which are orthogonal to the given vector $U = dfrac{-1}{4}i+dfrac{3}{2}j$, and these two vectors should be in opposite directions. This question is based on the concept of orthogonal vectors. If two vectors $A$ and $B$ have a dot product equal to zero, then the said two vectors […]
