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

Roads are often banked (see above) to make travelling around comers safer. In the case of a banked road where does the centripetal force come from?
Select one:
O a. The weight of the car
Ob. The reaction force
O Friction
Answer:
A highway corner of radius 350 m is banked at 15.
