A particle is going around in a circular path with constant speed. Angular momentum of particle is conserved about

Options

A. a point on the circumference of the circle
B. any point inside the circle on the plane of the circle.
C. about any point outside the circle on the plane of the circle
D. about centre of the circle

Explanation

To solve the problem of determining where the angular momentum of a particle moving in a circular path with constant speed is conserved, we can follow these steps:

### Step 1: Understand the Concept of Angular Momentum
Angular momentum (L) of a particle is given by the formula:
\[ L = r \times p \]
where \( r \) is the position vector from the point about which we are calculating the angular momentum to the particle, and \( p \) is the linear momentum of the particle.

### Step 2: Identify Conditions for Conservation of Angular Momentum
