Aproton And Particle Are Accelerated Using Same Potential Difference

Aproton and an a-particle are accelerated, using the same potential difference. How are the de-Broglie wavelengths λp and λα related…

Answers:

i.e., wavelength of proton is √8 times wavelength of α – particle.
Important point :
De-Broglie wavelength associated with the charged particles : The energy of a charged particle accelerated through potential difference V is
