This is a tad odd as there is no mention of this in my course. I suppose that what you are saying is that when when the centripital acceleration > gravitational acceleration then the person would fly off?
You are supposed to be able to apply your knowledge to a range of problems. In this case you are expected to work out for yourself that condition, using your knowledge of forces.

That's right, though I might say that, when
the force needed to give the required centripetal acceleration > the force provided by gravity
then the person will not be held in a circular path on the surface of the earth.

Changing to refer to accelerations, answers your earlier problem about the person's mass: both forces are proportional to mass, so you cancel the mass from the forces and are left with the accelerations.


Edit: Anyhow, what result do you get when you solve your equation,
centripital acceleration > gravitational acceleration
