Kurt owns a particle (6.0 g) that he shoots at 4.0 km/s into the xy plane, in a region with a nk uniform magnetic field given by 5.0 i mt. at one instant, he notices that when the particle's velocity is directed 37â° counterclockwise from the positive direction of the x axis, the magnetic force on the particle is 0.48 k n. k fo a. what is the particle's charge? definite your coordinate system and draw the details of the 2 right-hand rule that support your choice of positive or negative charge. the magnetic field? the directions must be clearly depicted in the diagram! particle's () radius, (i) cyclotron frequency, and (i) pitch in b. what will kurt measure for the c. draw a diagram that is a good representation of the helical trajectory of the particle.
