An electron is moving vertically downwards. If it passes through a magnetic field which is directed from south to north in a horizontal plane, then in which direction the electron would be deflected?

Explanation

To determine the direction in which the electron would be deflected when it passes through a magnetic field, we can use the right-hand rule for the magnetic force on a charged particle. Here’s a step-by-step solution:

### Step 1: Identify the Direction of the Electron's Motion
The electron is moving vertically downwards. We can represent this direction as downward (let's say towards the ground).

### Step 2: Identify the Direction of the Magnetic Field
The magnetic field is directed from south to north in a horizontal plane. We can represent this direction as horizontal, pointing towards the north.
