A negatively charged particle of mass 5.00 Ã 1019 kg is moving with a speed of 35.0

A negatively charged particle of mass 5.00 × 10ˆ’19 kg is moving with a speed of 35.0 m/s when it enters the region between two parallel capacitor plates. The initial velocity of the charge is parallel to the plate surfaces and in the positive x -direction. The plates are square with a side of 1.00 cm and the voltage across the plates is 3.00 V. If the particle is initially 1.00 mm from both plates, and it just barely clears the positive plate after traveling 1.00 cm through the region between the plates, how many excess electrons are on the particle? You may ignore gravitational and edge effects.
