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)?

A point charge q1 = +5.00 μCoul is held in fixed space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00*10^-3 kg and charge q2 = +2.00 μCoul is fired toward the fixed charge with an initial speed of 50.0 m/s. Gravity can be neglected. What is the distance between the two charges when the speed of the moving charge q2 is 20.0 m/s?

A charge of Q₁ = -3.0 μC is fixed in place. From a horizontal distance of S = 0.045m a particle of mass m = 7.2x10-³ kg and charge Q₂ = -8.0 μC is fired with an initial speed of Vo = 65 m/s directly towards the fixed charge Q1. What is the minimum distance between Q₁ and Q₂ before Q₁ flips its direction of motion?

Suppose the electric field between the plates is E (it is uniform and points only in the y direction). NOTE: Express your answers in terms of the given variables, using e for the fundamental charge and me for the mass of an electron. (a) What is the magnitude of the acceleration of the electron?

Consider an electron, of charge magnitude e = 1.602 × 10-1⁹ C and mass m₂ = 9.11 × 10-31 kg, moving in an electric field with an electric field magnitude E = 4 x 10² N/C, similar to what Thana observed in the simulation. Let the length of the plates be L = 50 cm, and the distance between them be d = 20 cm. Find the maximum speed, v, the electron could be moving if it enters the space halfway between and parallel to the two plates to just barely strike one of the plates. m/s If the field is pointing upward, which plate will Thana conclude the electron strikes at this speed? O The upper plate, because the electron charge magnitude is positive. O The upper plate, because we are only considering the magnitude of the electron charge, and magnitudes are always positive. O The lower plate, because the electron is attracted to the negative plate. O The lower plate, because the electron is negatively charged.
