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 0.180 T, the speed of the particle is 12.0 × 106 m/s, the radius of the trajectory of the path is 105.0 cm, and the charge has a magnitude of 3.20 × 10-19 C, determine the following. (a) sign of the charged particle positive O negative (b) mass of the particle (use the conversion 1 u = 1.66 x 10-27 kg) What kind of force must the particle experience in order to travel in a circle? What force provides the centripetal force needed to make the particle travel in a circle? What is the angle between the direction of the velocity of the particle and the direction of the magnetic field experienced by the particle? u
