In an experiment similar to the setup described in the Example, a positively charged particle of mass m is released from rest at the surface of the positive plate. The velocity of the particle at the negative plate is 1.30 ✕ 105 m/s. If the electric field magnitude is 6.00 ✕ 103 N/C, the distance between the two plates is 5 cm, and the charge on the particle is 3e, what is the particle's mass (in kg)?
