Moment of inertia of a body is 1 kg m2. If the body makes 2 revolutions per second, when its angular momentum is

Options

A. `2 pi Js`
B. `4 pi Js`
C. `pi//2Js`
D. `pi Js`

Explanation

To find the angular momentum of a body given its moment of inertia and its rotational speed, we can follow these steps:

### Step 1: Identify the given values
- Moment of inertia (I) = 1 kg·m²
- Frequency (f) = 2 revolutions per second

### Step 2: Convert frequency to angular velocity
Angular velocity (ω) can be calculated using the formula:
