If a particle of charge q is moving with velocity v along the y-axis and the magnetic field B is acting along the z-axis, use the expression `vecF=q(vecvxxvecB)` to find the direction of the force `vecF` acting on it.

Explanation

To find the direction of the force \( \vec{F} \) acting on a charged particle moving in a magnetic field, we can use the expression \( \vec{F} = q (\vec{v} \times \vec{B}) \). Here’s a step-by-step solution:

### Step 1: Identify the vectors
- The velocity vector \( \vec{v} \) of the particle is along the y-axis. We can represent this as:
\[ \vec{v} = v \hat{j} \]
where \( \hat{j} \) is the unit vector in the y-direction.
