The angular momentum of the electron, according to Bohr's model , is the whole number multiple of ………

Explanation

To solve the question regarding the angular momentum of the electron according to Bohr's model, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Bohr's Model**: According to Bohr's model, electrons revolve around the nucleus in circular orbits. Each orbit corresponds to a specific energy level.

2. **Angular Momentum Definition**: The angular momentum (L) of an electron in orbit can be defined as the product of its mass (m), velocity (v), and the radius (r) of its circular path. Mathematically, this is expressed as:
\[
