A proton and deuteron are accelerated by same potential difference.Find the ratio of their de-Broglie wavelengths.

Explanation

To find the ratio of the de-Broglie wavelengths of a proton and a deuteron when both are accelerated by the same potential difference, we can follow these steps:

### Step 1: Understand the de-Broglie wavelength formula
The de-Broglie wavelength (λ) is given by the formula:
\[ \lambda = \frac{h}{p} \]
where \( h \) is Planck's constant and \( p \) is the momentum of the particle.
