N = mg + F sin 30° =700+200 × (1/2)=800 newton.

Q. As shown in figure, a $70 k g$ garden roller is pushed with a force of $F = 200 N$ at an angle of $3 0^{\circ}$ with horizontal. The normal reaction on the roller is (Given $g = 10 m s^{- 2}$ )

$800 N$

$600 N$

$2003 N$

$8002 N$

$N = m g + F sin 3 0^{\circ}$
$= 700 + 200 \times \frac{1}{2} = 800$ newton.
