To determine the direction in which a negative charge particle will be deflected when moving in a magnetic field, we can use the right-hand rule for the Lorentz force. However, since the particle is negatively charged, we'll need to consider the direction of force opposite to what the right-hand rule would normally give for a positive charge. Let's break this down step-by-step: 1. Direction of Velocity: The particle is moving upward. 2. Direction of Magnetic Field: The magnetic field is pointing towards the north. According to the right-hand rule for a positive charge: 1. Point your thumb in the direction of the velocity (upward). 2. Point your fingers in the direction of the magnetic field (north). 3. Your palm will point in the direction of the force on a positive charge (west). Since we are dealing with a negative charge, the force will be in the opposite direction of what the right-hand rule gives us. Therefore, the force will point to the east. So, the negative charge particle will be deflected towards the east. The correct answer is: Option C: East
