Write the expression for the de-Broglie wavelength associated with a charged particle having charge 'q' and mass 'm' when it is accelerated by a potential V.

Explanation

To derive the expression for the de-Broglie wavelength associated with a charged particle having charge 'q' and mass 'm' when it is accelerated by a potential 'V', we can follow these steps:

### Step-by-Step Solution:

1. **Understanding de-Broglie Wavelength**:
The de-Broglie wavelength (\( \lambda \)) is given by the formula:
\[
\lambda = \frac{h}{p}
