Question
A proton and an α-particle, moving with the same velocity, enter a uniform magnetic field, acting normal to the plan of their motion. the ratio of the radii of the circular paths described by the proton and α-particle is :
Options
A.1 : 2
B.1 : 4
C.4 : 1
D.1 : 16
Solution
When a charged particle enters a field, it takes a circular enters a field, it takes a circular path. The radius of circular path is given by the relation
r =
For proton, r1 =
For α- particle, r2 =
⇒ r1 : r2 : : 1 : 2
r =
For proton, r1 =
For α- particle, r2 =
⇒ r1 : r2 : : 1 : 2
