A charged particle (mass = 4.0 g, charge = 5.0 C) moves in a region where the only force on it is magnetic. What is the magnitude of the acceleration of the particle at a point where the speed of the particle is 5.0 km/s, the magnitude of the magnetic field is 8.0 mT, and the angle between the direction of the magnetic field and the velocity of the particle is 60?
a. 39 km/s2
b. 43 km/s2
c. 48 km/s2
d. 52 km/s2
e. 25 km/s2

a. Bx is positive.
b. Bz is positive.
c. By is negative.
d. By is positive.
e. Bx is negative.
