*This is a question on a physics document, but beings it's also a mathematics question, it's been tagged as mathematics. Please show your work!* A 7.12 µC charge is moving at one half the speed of light perpendicular to a magnetic field of 4.02 mT. How large is the force on the charge?

A.) 4.29 N

B.) 32.90 x 10^(1) N

C.) 4.29 x 10^(12) N

D.) 1.00 x 10^(16) N

The correct option is A: 4.29 N.

Step-by-step explanation:

The magnetic force is given by:

Where:

q: is the charge = 7.12x10⁻⁶ C

v: is the speed = c/2 = 1.5x10⁸ m/s

B: is the magnetic field = 4.02x10⁻³ T

θ: is the angle = 90° (the speed is perpendicular to the magnetic field)

Hence, the force on the charge is:

Therefore, the correct option is A: 4.29 N.
