An electron horizontally enters the electric field as shown. Its entry velocity is

• purely vertical

• purely horizontal

• both vertical and horizontal

• neither vertical nor horizontal

As the electron travels through the electric field, its acceleration is

• purely in the leftward direction

• purely in the rightward direction

• purely in the upward direction

• purely in the downward direction

If the electric field between the plates has a strength of 145 N/C, what will be the magnitude of the electron's acceleration as it travels through the field?

• 1.7 * 10¹³ m/s² [up]

• 1.7 * 10¹³ m/s² [down]

• 2.5 * 10¹³ m/s² [up]

• 2.5 * m/s² [down]

If the electron enters the electric field with an initial velocity of 7.2 * 10⁴ m/s [right] and travels the length of the plates (4.2 cm), how long will it take for the electron to exit the electric field?

• 5.8 * 10^-7 s

• 5.8 * 10^-4 s

• 1.7 * 10⁶ s

• 1.7 * 10⁴ s

If an electron has a vertical acceleration of 6.4 * 10¹² m/s² [up] and takes 8.3 * 10^-8 s to traverse through the plates, what will its vertical displacement be at the end of its journey through the electric field?

• 0.058 m [down]

• 0.058 m [up]

• 0.022 m [down]

• 0.022 m [up]
