Question

A proton (mass m and charge + e) and an alpha
particle (mass 4 m and charge + 2e) are projected
with the same kinetic energy at right angles to a
uniform magnetic field. Which one of the
following statements will be true?
(a) the alpha-particle will be bent in a circular
path with a smaller radius than that of the
proton
(b) the radius of the path of the alpha-particle
will be greater than that of the proton
(c) the alpha-particle and the proton will be
bent in a circular path with the same radius
(d) the alpha-particle and the proton will go
through the field in a straight line
19. An electron having a charge e moves

Answer 1

The answer is c as the proton and alpha particle have the same kinetic energy

Answer 2

Answer:

option b is true

raidus directly related to mass
