A charged particle enters a region of uniform magnetic field at an angle of `85^@` to the magnetic line of force. The path of the particle is a circle. Is this statement true or false?

Explanation

To determine whether the statement "A charged particle enters a region of uniform magnetic field at an angle of 85 degrees to the magnetic line of force. The path of the particle is a circle" is true or false, we can analyze the motion of the charged particle in a magnetic field step by step.

### Step-by-Step Solution:

1. **Understanding the Motion of a Charged Particle in a Magnetic Field**:
- A charged particle moving in a magnetic field experiences a magnetic force that is given by the equation:
\[
\vec{F} = q(\vec{v} \times \vec{B})
