Activity 1

1. A particle with a mass of 0.785g carries a charge of 5.0 x 10C. The particle has a velocity of 6.05 x 10m/s due east. What is the magnitude and direction of the magnetic field if the magnetic force is equal to the weight of the change?

2. A particle with a charge of -3.0 x 10C is moving with a velocity of 4.0 x 10 m/s at an angle of 50 counter clockwise from the positive x-axis. What is the magnitude and direction of the force exerted on this particle by a magnetic field of 2.0 T?
