Trajectories of a set of particles, which are confined in the equatorial plane and conduct plane motions. The spin and electric charge of the black hole are 0.96 and 0.1, respectively. The electric charges of particles are ε₊ (top panel) and ε₋ (bottom panel). The initial physical speed of the particles is isotropical and equal to 0.35 with respect to the LNRF. The initial coordinates of the particles are r = 5 r_g, θ = 90°, and φ = 0. A circle at the left represents the event horizon.
