Magnetic Force on a Charged Particle
A particle with an elementary charge of |q| = 1.6 × 10⁻¹⁹ C moves through a region containing a uniform electric field of E = 3.0 × 10⁴ N/C and a uniform magnetic field of B = 0.25 T. If the particle has a velocity of 1.5 × 10⁵ m/s at an angle of 30° with respect to the magnetic field, what is the magnitude of the magnetic force acting on the particle?
A
7.5 × 10^-16 N
B
6.0 × 10^-15 N
C
3.0 × 10^-15 N
D
1.9 × 10^-15 N
