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

Part 1:
1. What is providing the centripetal force in Part 1?
2. How should the slope relate to the values of the mass of the rotating object, m and
the radius of the circular path, r?
