[-/2 Points] DETAILS OSUNIPHYS1 28.3.WA.012. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER As shown in the figure below, when a charged particle enters a region of magnetic field traveling in a direction perpendicular to the field, it will travel in a circular path. If the magnitude of the magnetic field is 0.170 T, the speed of the particle is 12.0 x 10 m/s, the radius of the trajectory of the path is 103.0 cm, and the charge has a magnitude of 3.20 x 10" C, determine the following O B O . O K O O (a) sign of the charged particle positive negative (b) mass of the particle (Use the conversion 1 u = 1.66 x 10-27 kg.)
