The two charged particles are moving with equivalent velocities of 7.60 m/s in the +x-direction. At one moment of time the first particle with a charge of -7.90 µC is placed at x = 0 and y = +9.00 cm, and the second particle with a charge of -2.70 µC is placed at x = 0 and y = -9.00 cm.
Determine the y-component of the magnetic force on the initial particle due to the second?
