Plot a graph showing variation of de-broglie wavelength `lambda` versus `1//sqrtV`, where V is accelerating potential for two particle A and P carrying same charge but of masses `m_1 and m_2(m_1gtm_2)`. Which one of the two represents a particle of smaller mass and why?

Explanation

To solve the problem, we need to analyze the relationship between the de Broglie wavelength (λ) and the accelerating potential (V) for two particles A and B with different masses but the same charge. Let's go through the steps to derive the relationship and plot the graph.

### Step 1: Write the formula for de Broglie wavelength
The de Broglie wavelength (λ) of a particle is given by the formula:

\[ \lambda = \frac{h}{p} \]
