Electrons Traveling at a Speed of V₀ = 3 ×

question 76

Multiple Choice

Electrons traveling at a speed of v₀ = 3 × 10⁷ m/s pass through the deflection plates. The electric field between the plates is E = 5000 V/m and spans a distance of x₁ = 5 cm. The electrons then travel a further distance of x₂ = 40 cm along the x-axis. With the magnetic field turned off, the total deflection in the y direction is

• A) 1.22 × 10^-3 m.
• B) 1.95 × 10^-2 m.
• C) 2.07 × 10^-2 m.
• D) 9.50 × 10^-3 m.
• E) 1.38 × 10^-2 m.
