What is the direction of the force acting on a charged particle q, moving with a velocity `vec(v)` a uniform magnetic field `vec(B)` ?

Explanation

To determine the direction of the force acting on a charged particle \( q \) moving with a velocity \( \vec{v} \) in a uniform magnetic field \( \vec{B} \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Force Equation**: The force \( \vec{F} \) acting on a charged particle in a magnetic field is given by the equation:
\[ \vec{F} = q (\vec{v} \times \vec{B}) \]
