Short Answer
As shown in the figure,a small particle of charge q = -7.0 × 10-6 C and mass m = 3.1 × 10-12 kg has velocity v0 = 9.4 × 103 m/s as it enters a region of uniform magnetic field.The particle is observed to travel in the semicircular path shown,with radius R = 5.0 cm.Calculate the magnitude and direction of the magnetic field in the region.
