A small block of weight 12 N is at rest on a smooth plane inclined at \(40 ^ { \circ }\) to the horizontal. The block is held in equilibrium by a force of magnitude \(P \mathrm {~N}\). Find the value of \(P\) when
- the force is parallel to the plane as in Fig. 1,
- the force is horizontal as in Fig. 2.
