Prob. 8 Extra Credit. A small particle of charge q = - 5.0 ×10-6 C and mass m = 4.5x1012 kgmoving with speed v = 2.0x104 m/s enters a region of uniform magnetic field, as shown in thediagram. The particle is observed to travel in the semicircular path shown, with radius R =3.0cm. The B-field is perpendicular to the velocity of the particle.[b] What is the magnitude ( in units of T)of the B-field? (Example: If your answer is B = 1.2 T,enter your answer as 1.2 in the answer box).
