A stone of mass 'm' is rotated in a circular path with a uniform speed by tying a string with the help of your hand. Answer the following questions :
What kind of force acts on the hand and state its direction?

Explanation

To solve the question regarding the force acting on the hand when a stone is rotated in a circular path, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Circular Motion**: When an object, such as a stone, is rotated in a circular path, it experiences a force that keeps it moving in that circular path. This force is known as the centripetal force.

2. **Identifying the Forces**: In this scenario, the stone is tied to a string, and as it rotates, it exerts an outward force on the string due to its inertia. This is often referred to as the centrifugal force, which is not a real force but rather a perceived effect due to the inertia of the stone.
