Physics

To find the speed of the mass at the end of the string in a conical pendulum, we can follow these steps:

 

1. Identify the components of the forces:

The gravitational force acting on the mass is .

The tension in the string provides the centripetal force required for circular motion.

 

2. Calculate the vertical and horizontal components:

The length of the string and the angle .

The vertical component of the tension balances the weight:

The horizontal component provides the centripetal force:

 

3. Calculate the radius of the circular path:

 

4. Using the balance of forces to find the tension :
