What is the ratio of magnitude of potential energy to the kinetic energy for an electron in hydrogen atom ?

Explanation

To find the ratio of the magnitude of potential energy to the kinetic energy for an electron in a hydrogen atom, we will follow these steps:

### Step 1: Understand the Forces Acting on the Electron
The electron in a hydrogen atom is in circular motion around the nucleus (proton). The centripetal force required for this circular motion is provided by the electrostatic force of attraction between the negatively charged electron and the positively charged nucleus.

### Step 2: Write the Expression for Centripetal Force
The centripetal force \( F_c \) acting on the electron can be expressed as:
\[
