Question: Draw the Reaction Force at point P.
My Attempt and Reasoning: Since the Reaction or the Normal Force is normal to the surface the solution according to me should be-
I don't understand why is this true? The question mentioned that the Force F acts in such a manner so that the system in equilibrium. In that case, the Part D. seems to be correct as it is opposite to the direction of the vectorial sum of the Force F and W. In general should one know whether a system is in equilibrium to find out the direction of the Reaction Force or is there a direct rule that allows us to find the direction?
