As shown in the figure, a small particle of charge q = -7.0 Times 10-6 C and mass m = 3.1 Times 10-12 kg has a velocity v0 = 9.4 Times 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. Region of magnetic field Path of the particle.
