Unit vectors have a magnitude of 1. The basic unit vectors are \(i = \left( \begin{array}{l}1\\ 0\\0\end{array} \right)\), \(j=\left(\begin{array}{l}0\\1\\0\end{array ...

the greatest (maximum) resultant is equal to their sum - this happens when forces act in the same direction the smallest (minimum) resultant is equal to their difference - this happens when forces act ...
