microscope consist of electric and magnetic fields that control the electron beam.

$($a$)$ the position of the electron

$y_f$

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. $m$

$($b$)$ the velocity of the electron

$v_f=$

Your response differs from the correct answer by more than $100\%.\frac{m}{s}$hat$()+$

$]\frac{m}{s}$hat$(j)$

$($c$)$ the speed of the electron

$|v_f|=2650000000$

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. $\frac{m}{s}$

$($d$)$ the direction of travel of the electron $($i$.$e$.$ the angle between its velocity and the $x$ axis$)$
