In Bohr's atomic model of hydrogen, let K, P and E are the kinetic energy, potential energy and total energy of the electron respectively. Choose the correct option when the electron undergoes transitions to a higher level :

Options

A. All K, P and E increase
B. K decreases, P and E increase
C. P decreases. K and E increase.
D. K increases, P and E decrease

Explanation

To solve the problem regarding the changes in kinetic energy (K), potential energy (P), and total energy (E) of an electron in a hydrogen atom when it transitions to a higher energy level, we can follow these steps:

### Step 1: Understand the Energy Relationships
In the Bohr model of the hydrogen atom, the total energy (E) of an electron in the nth orbit is given by the formula:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
where \( n \) is the principal quantum number.

### Step 2: Kinetic and Potential Energy
