Question

A charged particle of mass ‘m’ and charge ‘q’ is accelerated through a potential difference ‘V’. The De Broglie wavelength associated with the particle is

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

The kinetic energy of the charged particle is . The de Broglie wavelength in terms of kinetic energy is $\lambda =\frac{h}{\sqrt{2mK}}.$ Refer to text bookor material.}
