A Particle (Q = 5 $\mu$ G)moves in a Region Where the Magnetic Field Has Components

Multiple Choice

A particle (q = 5.0 nC,m = 3.0 $\mu$ g) moves in a region where the magnetic field has components B_x = 2.0 mT,B_y = 3.0 mT,and B_z = -4.0 mT.At an instant when the speed of the particle is 5.0 km/s and the direction of its velocity is 120 $\degree$ relative to the magnetic field,what is the magnitude of the acceleration of the particle?

A) 33 m/s²
B) 17 m/s²
C) 39 m/s²
D) 25 m/s²
E) 45 m/s²
