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 can follow these steps:

### Step 1: Understand the Potential Energy (PE) and Kinetic Energy (KE) in the Hydrogen Atom
In the Bohr model of the hydrogen atom, the potential energy (PE) of the electron is given by the formula:
\[ PE = -\frac{k e^2}{r} \]
where \( k \) is Coulomb's constant, \( e \) is the charge of the electron, and \( r \) is the radius of the electron's orbit.
