#### Question

A small coin is placed on a record rotating at \[33\frac{1}{3}\] rev/minute. The coin does not slip on the record. Where does it get the required centripetal force from ?

#### Solution

The coin gets the required centripetal force from the frictional force between the coin and the record.
