An electron moves round the nucleus of an atom, in a circular path. What is the direction of the angular momentum of the electron ?

Explanation

To determine the direction of the angular momentum of an electron moving in a circular path around the nucleus of an atom, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Angular Momentum**:
Angular momentum (\( \vec{L} \)) is a vector quantity that depends on the position vector (\( \vec{r} \)) and the linear momentum (\( \vec{p} \)) of the particle. For a particle moving in a circular path, it can be expressed as:
\[
\vec{L} = \vec{r} \times \vec{p}
