Question

A proton and α- particle are projected with the same

velocity normal to a uniform magnetic field. The ratio of

the magnetic Lorentz force experienced by the proton

and the α particle is

(a) 1 : 1 (b) 1 : 2 (c) 2 : 1 (d) 1 : 0

Answer it correctly.​

Answer 1

Answer:

when a charged particle enters a field, it takes a circular path. the radius of circular path is given by the relation.

r=mv/ Bq

for proton, r1=mv/Bq

for a-particle, r2= '4m times 'v'/B times 2q

= 2mv/Bq

»» r1 : r2:: 1:2
