A charged particle is moving in a uniform magnetic field in a circular path of radius 'R'. When the energy of the particle becomes three times the original, the new radius will be
Options
- AR 3
- BR
- C3 R
- D3 R
Correct answer
D. 3 R
Step-by-step solution
Bqv = mv ² R R = mv qB 1 2 mv ₂²=3 1 2 mv ₁² v ₂= 3 v ₁ R ₂= 3 mv q B = 3 R
