A pair of charged conducting plates produces a uniform field of 12,000 N/C, directed to the right, between the plates. The separation of the plates is 40 mm. In the following figure an electron is projected from plate A, directly toward plate B, with an initial velocity of vo = 2.0 × 107 m/s. The velocity of the electron as it strikes plate B is closest to: A) 1.2 × 107 m/s B) 1.5 × 107 m/s C) 1.8 × 107 m/s D) 2.1 × 107 m/s E) 2.4 × 107 m/s

An electric field with a magnitude of 4800 N/C is directed parallel to the positive y-axis. A particle with a charge of q= 3.2 µC and a mass of 4.2 mg is initially at rest and parallel to the electric field. What is the acceleration of the particle if it is released from rest? (Ignore the effect of gravity) 2.8 m/s^2 15.8 m/s^2 0.97 m/s^2 3.7 m/s^2

A pair of vertical charged conducting plates produces a uniform field of 1.1 Nî, directed to the right, between the plates. The separation of the kN plates is 40mm.

An electron and a proton are separated by a distance of 1.9 x 10-10 m (roughly the diameter of a single atom). The masses of the electron and proton are me = 9.11 x 10- kg and 1.673 × 10-2' kg, respectively. The elementary charge mp e = 1.602 x 10-19 C. The universal gravitational constant G = 6.67 x 10 N-m²/kg² and the coulomb constant k = 8.988 × 10° N-m²/C2. What is the magnitude F, of the electric force between the electron and the proton? Fe= N. What is the magnitude F, of the gravitational force between the electron and the proton? Fg In this scenario, how many times stronger is the electric force than the gravitational force?
