A charged particle moving along a straight line path enters a uniform magnetic field of 4 mT at right angles to the direction of the magnetic field. If the specific charge of the charged particle is 8 10^7 C kg ⁻¹ , the angular velocity of the particle in the magnetic field is
Options
- A64 10^4 rad s ⁻¹
- B32 10^4 rad s ⁻¹
- C16 10^4 rad s ⁻¹
- D48 10^4 rad s ⁻¹
Correct answer
B. 32 10^4 rad s ⁻¹
Step-by-step solution
B=4 mT =4 10⁻³ ~T , q m =8 10^7 c kg ⁻¹ Angular velocity, w = B _ q m =4 10⁻³ 8 10^7=32 10^4 rad s ⁻¹
