Adjoining figure shows a force of \( 40 \mathrm{~N} \) acting at \( 30^{\circ} \) to the horizontal on a body of mass \( 5 \mathrm{~kg} \) resting on a smooth horizontal surface. Assuming that the acceleration of free-fall is \( 10 \mathrm{~ms}^{-2} \), which of the following statements \( \mathrm{A}, \mathrm{B}, \mathrm{C} \), \( \mathrm{D} \) is (are) correct?
\( \mathrm{P} \)
[1] The horizontal force acting on the body is \( 20 \mathrm{~N} \)
[2] The weight of the \( 5 \mathrm{~kg} \) mass acts vertically downwards
[3] The net vertical force acting on the body is \( 30 \mathrm{~N} \)
(A) \( 1,2,3 \)
(B) 1,2
(C) 2 only
(D) 1 only
