Question

A proton, a deuteron and an alpha particle are accelerated through same potential difference and then they enter a normal uniform magnetic field, the ratio of their kinetic energies will be

Answer 1

Answer:

Explanation:

Kinetic energy gained by charged particle of charge q when accelerated under a potential difference V will be KE=qV

For a given V,KE∝q

For proton, deuteron and α-particle the ratio of charges is 1:1:2
