Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Hello, could you please help me with this question. I need second (In what direction must the force (tension) act on the yo-yo?), and third ( What exerts the force?)

2. You swing a yo-yo about your head in a horizontal circle, then you swing another one with twice the mass, and
twice as fast with the same string. How do the tensions in the strings differ? In what direction must the force
(tension) act on the yo-yo? What exerts the force?
