Two positively charged particles 1 and 2 are moving in the same plane, with the velocity of particle 1 perpendicular to the velocity of particle 2. At the instant shown in Figure P28.9, particle 2 is on the line that defines the velocity of Figure P28.9 particle 1. (Take their speeds to be much less than \(c_{0}\).) For this instant, describe and sketch the direction of the magnetic force that each particle exerts on the other.
