Answer

The centripetal force required at the edge is larger.

Work Step by Step

We have $$F_c=m\omega^2r$$ Both the center and the edge of the turntable have the same angular frequency $\omega$. The edge, however, has a greater radius of rotation circle $r$. Therefore, the centripetal force required at the edge would be larger.
