A charged particle when enters a uniform magnetic field moves in a helical path. If its angular velócity is 4 10^6 rads ⁻¹ and its velocity in the direction of magnetic field is 3 10^5 ~ms ⁻¹ then the pitch of the helix is
Options
- A5 ~cm
- B10 ~cm
- C15 ~cm
- D20 ~cm
Correct answer
C. 15 ~cm
Step-by-step solution
Angular velocity, =4 10^6 rad / s Velocity of changes particle, v=3 10^5 ~m / s Pitch of the helix = v t =3 10^5 2 aligned & =3 10^5 2 4 10^6 & =15 ~cm aligned
