2. A particle of mass 1.7 x 10-27 kg and charge +1.6 x 10-19 C enters a uniform magnetic fieldof magnitude B = 5.0 mT. If the particle enters with a velocity v = 83.5 km/s in a directionperpendicular to the field: (a) Make a drawing of the particle path, including the force and the B field, (b) calculate the force F exerted on the particle, (c) find the radius R of the circular path, (d) find the time required for one revolution.
