A moving charged particle q travelling along the positive X-axis enters a uniform magnetic field B. When will the force acting on q be maximum?

Explanation

To determine when the force acting on a moving charged particle \( q \) in a uniform magnetic field \( B \) is maximum, we can follow these steps:

### Step 1: Understand the Force on a Charged Particle
The force \( F \) acting on a charged particle moving in a magnetic field is given by the formula:
\[ F = q v B \sin \theta \]
where:
