A small particle carrying a +47 ? C charge moves at 31m/s through a uniform 0.80

Question

A small particle carrying a +47?C charge moves at 31m/s through a uniform 0.80T magnetic field. The velocity and magnetic field are both in the xy-plane, with the velocity making a 20? angle and the magnetic field a 268? angle, both measured counterclockwise from the +x-axis.

Part A

Find the magnitude of the magnetic force on the particle.

Part B

Find the direction of the magnetic force on the particle.

Find the direction of the magnetic force on the particle.: (which one is true?

Explanation / Answer

q = +47 ?C, v = 31 m/s, B = 0.80 T, ? = 20?, ? = 268?

a) F = qvBsin[? + (360 - ?)] = 0.00108 N

b) -z direction
