Suppose a collision produces a pair of particles, an electron and a positron (antielectron). the two are both initially traveling at a velocity of 8.0E4i m/s. define their starting point as the origin of a coordinate system. the two particles experience uniform electric fields of 1.5E5j N/C over a distance of 5E-2m.
what is the electric force on the electron? (neglect the electric force due to the positron)
