Aproton travels at a speed of 2.0..*.10ò meters/second. its velocity is at right angles with a magnetic field of strength 5.5..*.10è³ tesla. what is the magnitude of the magnetic force on the proton?

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?
