Would the Bohr formula for the H-atom remain unchanged if proton had a charge `(+4//3) e` and electron a charge `(-3//4) e`, where `e = 1.6 xx 10^(-19) C`. Given reasons for you answer.

Explanation

To determine whether the Bohr formula for the hydrogen atom remains unchanged when the proton has a charge of \( +\frac{4}{3} e \) and the electron has a charge of \( -\frac{3}{4} e \), we can analyze the situation step by step.

### Step 1: Understand the Bohr Model
The Bohr model describes the hydrogen atom as an electron revolving around a nucleus (proton) due to the electrostatic force of attraction between them. The key equation in the Bohr model relates the electrostatic force to the centripetal force required to keep the electron in circular motion.

### Step 2: Write the Electrostatic Force Equation
The electrostatic force \( F \) between two charges \( Q_1 \) and \( Q_2 \) separated by a distance \( r \) is given by Coulomb's law:
\[
