In the figure provided, for the charged particle entering the magnetic field, what is the initial direction of deflection? Left Up Right Down

To determine the initial direction of deflection of a charged particle moving in a magnetic field, we can use the right-hand rule, which helps to establish the direction of the force acting on a moving charge in a magnetic field.

Step-by-Step Analysis:

1. Identify the Variables:

   • Direction of the magnetic field ($B$)
   • Velocity of the charged particle ($v$)
   • Charge of the particle (positive or negative)

2. Use the Right-Hand Rule:

   • Point your thumb in the direction of the velocity ($v$) of the particle.
   • Curl your fingers in the direction of the magnetic field ($B$).
   • The direction your palm faces indicates the direction of the force ($F$) acting on a positive charge. For a negative charge, the force is in the opposite direction.

3. Determine the Force Direction: Based on the above rules, identify the resulting force direction which indicates the initial direction of deflection.

Final Answer:

Without specific details about the directions of the velocity and magnetic field in the figure, we can't give a definitive answer. However, using the right-hand rule as described, you can determine whether the deflection is to the Left, Up, Right, or Down based on the directions given in your figure.
