Step 1
Given:
To explain the correct statement among the given statement as,
Step 2
Explanation:
A de-Broglie wavelength is given as,
$\lambda =\frac{h}{mv}$
Here, the mass of the electron is less hence the velocity will be more.
Therefore, the correct option is c. The electron is having the highest speed and the momentum of these particles.
