A charged particle is free to move in an electric field. Will it always move along electric lines of force?

Explanation

To address the question of whether a charged particle will always move along electric lines of force when free to move in an electric field, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Electric Field Lines**: Electric field lines represent the direction of the electric field at various points in space. The direction of the electric field is defined as the direction a positive test charge would move if placed in the field.

2. **Behavior of a Charged Particle at Rest**: If a charged particle (let's say a positive charge) is at rest in an electric field, it will experience a force due to the electric field. The force acting on a charged particle is given by \( F = qE \), where \( q \) is the charge and \( E \) is the electric field strength. Since the particle is at rest, it will start to move in the direction of the electric field lines.
