The figure below shows an electron at the origin that is
released with initial speed v0 = 3.5 ✕ 106 m/s at an angle θ0 = 45°
between the plates of a parallel plate capacitor of plate
separation D = 2.0 mm. If the potential difference between the
plates is ΔV = 185 V, calculate the closest proximity, d, of the
electron to the bottom plate (in mm).
Homework Answers
Force on the electron
F=qE =q(V/D) =(1.6*10-19)(185/2*10-3)
F=1.48*10-14 N
acceleration
ay=F/m =(1.48*10-14)/(9.11*10-31) =1.6246*1016 m/s2
From
Vy2=Voy2+2ayy
0 =(-3.5*106Sin45)2+2*1.6246*1016*y
y=-1.885*10-4 m=-0.1885 mm
It will reach
d=(3/2) -0.1885
d=1.3115 mm

An electron is projected with an initial speed v0 = 4.80x106 m/s into the uniform field between the parallel plates in(Figure 1). The direction of the field is vertically downward, and the field is zero except in the space between the two plates. Part A If the electron just misses the upper plate as it emerges from the field, find the magnitude of the electric field.

An electron is released between the plates of a charged
parallel-plate capacitor very close to the right-hand plate. Just
as it reaches the left-hand plate, its speed is v.
If the distance between the plates were halved without changing
the electric potential between them, then the speed of the electron
when it reached the left-hand plate would be
a) 2v
b) sqrt2v
c) v
d) v/sqrt2
e) v/2
