Question

The de-Broglie wavelength associated with a moving charged particle does not depend on its_____

• A. Mass
• B. Charge
• C. Velocity
• D. Momentum

Answer 1

The correct option is B Charge

de-Broglie wavelength associated with the moving charged particle is given by $\lambda =\frac{h}{mv}=\frac{h}{p}$
where momentum $p=mv$
Thus $\lambda$ depends only on mass of particle, velocity of particle and its momentum but not on its charge.
