I'm guessing you have to show that the horizontal component of the force is bigger than Fmax
And so justify how that makes it move

If the horizontal component is less than then friction will be enough to oppose motion i.e. the friction will be equal to the force.

If the force is then friction will have reached it's limit and so the frictional force will be equal to .

It's not bigger... it's smaller.

I haven't done the question so I was "guessing". Obviously if I did do it then I'd find if it was bigger or smaller. And so I would know it moves or not
