A proton carrying 1 MeV kinetic energy is moving in a circular path of radius R in uniform magnetic field. What should be the energy of an - particle to describe a circle of same radius in the same field?
1 MeV
0.5 MeV
4 MeV
2 MeV
Radius of a particle moving in magnetic field is given by
E = Kinetic energy
Rproton = R-particle
=>
therefore, E= Ep= 1 MeV
Option 1)
1 MeV
this is the correct option
Option 2)
0.5 MeV
this is the incorrect option
Option 3)
4 MeV
this is the incorrect option
Option 4)
2 MeV
this is the incorrect option
