An electron is moving in an orbit in hydrogen atom of radius `0.5xx 10^(-10)` m. Calculate the time period of electron about the nucleus

Explanation

To find the time period of an electron moving in an orbit around a hydrogen nucleus, we can follow these steps:

### Step 1: Identify the given data
- Radius of the orbit \( r = 0.5 \times 10^{-10} \) m.

### Step 2: Use the formula for the time period of an electron in orbit
The time period \( T \) of an electron moving in a circular orbit is given by the formula:
\[
