Motion of a Charged Particle: a Pair of Charged Conducting

question 38

Multiple Choice

Motion of a charged particle: 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. An electron is projected from plate A, directly toward plate B, with an initial velocity of v_o = 1.0 × 10⁷ m/s, as shown in the figure. (e = 1.60 × 10^-19 C, ε₀ = 8.85 × 10^-12 C²/N ∙ m², m_el = 9.11 × 10^-31 kg) The distance of closest approach of the electron to plate B is nearest to

• A) 16 mm.
• B) 18 mm.
• C) 20 mm.
• D) 22 mm.
• E) 24 mm.
