A particle (q = -4.0 μC, m = 5.0 mg) moves in a uniform magnetic field. If the magnetic field strength is B,
the speed of the particle is v, and the angle that the particle’s velocity makes with the magnetic field direction
is q, in which of the following cases would the magnitude of the particle’s acceleration be the largest?

A. v = 2.0 km/s, B = 9.1 mT, q = 90°
B. v = 2.0 km/s, B = 8.2 mT, q = 90°
C. v = 6.0 km/s, B = 8.2 mT, q = 50°
D. v = 6.0 km/s, B = 8.2 mT, q = 0°
E. v = 6.0 km/s, B = 9.1 mT, q = 50°
