If total energy of the same electron is E, then what would be its kinetic energy and potential energy .

Explanation

To solve the problem of finding the kinetic energy (KE) and potential energy (PE) of an electron in a hydrogen atom when the total energy (E) is given, we can follow these steps:

### Step 1: Understand the Forces Acting on the Electron
In the Bohr model of the hydrogen atom, the electron revolves around the nucleus due to the electrostatic force of attraction between the positively charged nucleus and the negatively charged electron. This electrostatic force provides the necessary centripetal force for the electron's circular motion.

### Step 2: Set Up the Equation for Centripetal Force
The centripetal force acting on the electron can be expressed as:
\[
