Equal Charges, One at Rest, the Other Having a Velocity

question 25

Multiple Choice

Equal charges, one at rest, the other having a velocity of 10⁴ m/s, are released in a uniform magnetic field. Which charge has the largest force exerted on it by the magnetic field?

• A) The charge that is at rest.
• B) The charge that is moving, if its velocity is parallel to the magnetic field direction when it is released.
• C) The charge that is moving if its velocity makes an angle of 45^o with the direction of the magnetic field when it is released.
• D) The charge that is moving if its velocity is perpendicular to the magnetic field direction when it is released.
• E) All the charges above experience equal forces when released in the same magnetic field.
