A particle is moving on a circular path with speed given by v= ` alphat`, where `alpha` is a constant. Find the acceleration of the particle at the instant when it has covered the ` n^("th")` fraction of the circle.

Explanation

To solve the problem of finding the acceleration of a particle moving on a circular path with a speed given by \( v = \alpha t \), we will follow these steps:

### Step 1: Understand the motion
The particle is moving in a circular path and its speed increases linearly with time. The speed is given by:
\[ v = \alpha t \]
where \( \alpha \) is a constant.
