Two Large Conducting Parallel Plates a and B Are Separated

question 848

Multiple Choice

Two large conducting parallel plates A and B are separated by 2.4 m.A uniform field of 1500 V/m,in the positive x-direction,is produced by charges on the plates.The center plane at x = 0.00 m is an equipotential surface on which V = 0.An electron is projected from x = 0.00 m, with an initial velocity of 1.0 × 10⁷ m/s perpendicular to the plates in the positive x-direction,as shown in the figure.What is the kinetic energy of the electron as it reaches plate A? (e = 1.60 × 10^-19 C,m_el = 9.11 × 10^-31 kg)

• A) +2.4 × 10^-16 J
• B) +3.3 × 10^-16 J
• C) -2.4 × 10^-16 J
• D) -2.9 × 10^-16 J
• E) -3.3 × 10^-16 J
