How would you determine the magnitude of the magnetic field and the speed of q_2q2?
A charge q_1 = 20.0 µC moves with a speed of 4.00 ✕ 10^3 m /s perpendicular to a uniform magnetic field. The charge experiences a magnetic force of 7.46 ✕ 10^-3 N . A second charge q_2 = 7.00 µC travels at an angle of 40.0° with respect to the same magnetic field and experiences a 1.90 ✕ 10^-3 N force.

Explanation:
The force,
Where v= velocity of the particle.
So for
If moving at an angle,
So for
