Neco 2021 Physics Question 39
Practice objective / multiple choice question 39 from the 2021 Neco Physics examination.
A block is in static equilibrium under three forces shown in the force diagram. Force \(F_{1}\) acts horizontally to the left (magnitude unknown). Force \(F_{2}\) has a magnitude of \(20\) N and is directed \(30^{\circ}\) above the horizontal to the right. Force \(F_{3}\) acts vertically upward with unknown magnitude. The resultant of \(F_{2}\) and \(F_{3}\) makes an angle of \(45^{\circ}\) with the horizontal. Determine the magnitude of \(F_{1}\) (in newtons, to one decimal place).
