Two forces of magnitudes 20 N and \(F \mathrm {~N}\) act at a point \(P\) in the directions shown in the diagram.
- Given that the resultant force has no component in the \(y\)-direction, calculate the value of \(F\).
- Given instead that \(F = 10\), find the magnitude and direction of the resultant force.
