Two charged particles move in the same direction with respect to the same magnetic field. Particle 1 travels two times faster than particle 2. However, each particle experiences a magnetic force force of the same magnitude. Find the ratio qt/ q: of the magnitudes of the charges.
A charged particle carrying charge `q=1muc` moves in uniform magnetic with velocity `v_1=10^6m//s` at angle `45^@` with `x`-axis in the `xy`-plane and experiences a force `F_1=5sqrt2mN` along the negative `z`-axis. When te same particle moves with velocity `v_2=10^6m//s` along the `z`-axis it experiences a force `F_2` in `y`-direction. Find <br> a. the magnitude and direction of the magnetic field <br> b. the magnetic of the force `F_2`.
