An electron, a proton and an alpha particle having the same kinetic energy are moving in circular orbits of radii r e , r p , r α respectively in uniform magnetic field B. The relation between r e , r p , r α is:
Text Solution
Verified by ExpertsThe correct answer is:
D
Radius of circular path in magnetic field is given by

kinetic energy of particle
m = mass of particle
charge on particle
magnetic field intensity
R = radius of path
For electron
…… (i)
For proton
… ..(ii)
For 
particle
..(iii)
as 
so
