A charged particle q is moving in the presence of a magnetic field B which is inclined to an angle 30° with the direction of the motion of the particle. Draw the trajectory followed by the particle in the presence of the field and explain how the particle describes this path.

Explanation

To solve the problem of a charged particle \( q \) moving in a magnetic field \( B \) that is inclined at an angle of \( 30^\circ \) to the direction of the particle's motion, we can follow these steps:

### Step 1: Understanding the Forces Acting on the Particle
The force acting on a charged particle moving in a magnetic field is given by the Lorentz force equation:
\[ \mathbf{F} = q(\mathbf{v} \times \mathbf{B}) \]
where \( \mathbf{v} \) is the velocity of the particle and \( \mathbf{B} \) is the magnetic field. The angle \( \theta \) between the velocity and the magnetic field affects the magnitude of the force.
