A uniform electric field between two parallel plates has a
magnitude of 20 N/C and directed downward. Draw the E-field
indicating +/- signs which plate is positive and which plate is
negative?
The electric field between two parallel plates is uniform, with
magnitude 576 N/C. A proton is held stationary at the positive
plate, and an electron is held stationary at the negative plate.
The plate separation is 4.06 cm. At the same moment, both particles
are released.
(a)
Calculate the distance (in cm) from the positive plate at which
the two pass each other. Ignore the electrical attraction between
the proton and electron.
_______cm
(b)
Repeat part (a) for a sodium...
A uniform electric field of magnitude 40 N/C is directed downward. What are the magnitude and the direction of the force on a + 4C charge placed in this electric field? 160 N directed upward 160 N directed downward 10 N directed downward 0.1 N directed downward
A uniform electric field exists in the region between two
oppositely charged parallel plates 1.70cmapart. A proton is
released from rest at the surface of the positively charged plate
and strikes the surface of the opposite plate in a time interval

A pair of charged conducting plates produces a uniform field of
12,000 N/C, directed to the right, between the plates. The
separation of the plates is 40 mm. An electron is projected from
plate A, directly toward plate B, with an initial velocity of v0 =
2.0 x 107 m/ s, as shown in the figure. The velocity of the
electron as it strikes plate B is closest to a. 2.1 x 107 m/s b.

A uniform electric field with a magnitude of 6 × 10^6 N/C is
applied to a cube of edge length 0.1 m as seen in Fig 22-2 above.
If the direction of the E - field is along the +x-axis, what is the
electric flux passing through the shaded face of the cube?
Part A
An electron is moving east in a uniform electric field of 1.52
N/C directed to the west. At point A, the velocity of the
electron is 4.54×105 m/s pointed toward the east. What
is the speed of the electron when it reaches point B,
which is a distance of 0.360 m east of point A?
Part B
A proton is moving in the uniform electric field of part A. At
point A, the velocity of the proton is...
Two large parallel copper plates are 3.60 cm apart and have a
uniform electric field of magnitude E = 7.98 N/C between them (see
the figure). An electron is released from the negative plate at the
same time that a proton is released from the positive plate.
Neglect the force of the particles on each other and find their
distance from the positive plate when they pass each other.
