An electron is fired through a pair of deflection plates,which produce a 2.00 cm long region with an electric field of 4000 N/C perpendicular to the electron's initial velocity.If the initial speed of the electron is 1.00 $\times$ 10⁷ m/s,how long does it take to traverse the plates? A) 2.00 $ \mu$s B) 2.00 ns C) 1.70 ns D) 1.80 ns E) 1.50 $ \mu$s

Question

Quizplus · Accepted Answer

The time taken to traverse the plates is calculated by dividing the length of the plates by the initial speed of the electron: $ \frac{0.02 \, \text{m}}{1.00 \times 10^7 \, \text{m/s}} = 2.00 \times 10^{-9} \, \text{s} = 2.00 \, \text{ns} $.
