What is the normal component of weight?
ok, so what do you mean by component of weight? anyways, this is what i thought should be the answer F= mgsin(θ) is that correct?
Tilt your axis such that, Y is pointing to the opposite of Weight of M. And X is pointing towards the right. (like usual). [The axis shown in the diagram requires you to find Fnet, which I don't know how to find; thus use this method].
In that case,
Positive being up,
-W(of M)+Ncos50=0
=> N=Mg/cos50
plug your numbers, that's your answer.
