(C) The forces acting on the garden roller in the vertical direction are the normal reaction $N$ (upwards),the weight $mg$ (downwards),and the vertical component of the applied force $F \sin 30^{\circ}$ (downwards).Since the roller is in equilibrium in the vertical direction,the net force is zero:$N - mg - F \sin 30^{\circ} = 0$$N = mg + F \sin 30^{\circ}$Given $m = 70\,kg$,$g = 10\,m s^{-2}$,$F = 200\,N$,and $\sin 30^{\circ} = 0.5$:$N = (70 \times 10) + (200 \times \sin 30^{\circ})$$N = 700 + (200 \times 0.5)$$N = 700 + 100$$N = 800\,N$
