Please Help! ASAP! 1. A proton moves perpendicularly to a magnetic field that has a magnitude of 4.20 x 10-2 T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 X 10–14 N?

2. If an electron in an electron beam experiences a downward force of 2.0 x 10-14 N while traveling in a magnetic field of 8.3 x 10-2 T west, what is the direction and magnitude of the velocity?

3. A uniform 1.5 T magnetic field points north. If an electron moves vertically downward (toward the ground) with a speed of 2.5 X 107 m/s through this field, what force (magnitude and direction) will act on it?​
