## Homework Statement

The ball in this conical pendulum is moving at constant velocity.

The length of the string is 1m and the ball is 0.5kg.

Determine the tension in the string.

## Homework Equations

## The Attempt at a Solution

The force that the ball exerts on the string is the tension inside the string

and the ball experiences two different forces.

One is the force the ball experiences due to gravity and the other is the force it experiences

due to the circular motion that it's undergoing.

The resultant of these two forces will give the tension inside the string.

The force due to gravity can be calculated with F=m x a

But I'm unsure as to how the force on the ball due to the circular motion of the ball can be calculated.

Does anyone know how this can be done?
