What would be the change in radius of `n^"th"` orbit, if the mass of electron reduces to half of its original value ?

Explanation

To find the change in the radius of the nth orbit when the mass of the electron is reduced to half of its original value, we can follow these steps:

### Step 1: Understand the relationship between radius and mass
From Bohr's model of the atom, the radius of the nth orbit (R_n) is given by the formula:
\[ R_n = \frac{n^2 h^2}{4 \pi^2 k Z e^2 m} \]
where:
- \( n \) is the principal quantum number (orbit number),
- \( h \) is Planck's constant,
