Electric field mapping Lab Physics 2212k
1) Describe the central electric field (E) shape in the case of
two parallel plates.
2) Do the distances between adjacent equipotential lines between
the two parallel plates, approximately measure the same? Calculate
an average value for the magnitude of the electric field between
the plates.
3) Does the electric field extend beyond the edges of the plates
in the two parallel plates experiment?
4) Is it possible for two different equipotential lines or...
1 a) What is the approximate electric field strength and
magnetic field strength of the electromagnetic waves radiated by a
60-W lightbulb, as measured 5.5 m from the bulb? You can assume
that the bulb is 100% efficient in converting electrical energy to
light energy.
b.) Incandescent light bulbs are very inefficient. Find the
electric field strength and magnetic field strength assuming 5%
efficiency.
Please show all work, thank you!
Problem 1a: Velocity Selector: Show that with the right ratio of
electric to magnetic field strength a particle of velocity v will
proceed through both fields in a straight line at constant speed
(hint: you will need an equation containing v. Also: what does the
straight line at constant speed give you?). Assume that the angle
of the velocity vector relative to the magnetic field vector is 90
degrees.
b: Show mathematically that the charge magnitude and sign do not...
(a) Use Gauss’s Law for the electric field to show that the
electric field is discontinuous at the charged surface of a
conducting plane.
(b) Devise a way to apply this same approach to a patch on a
charged spherical conductor. Hint: Draw a diagram with the electric
field so you can specify the shape of the surface.

An electron is to be accelerated in a uniform electric field
having a strength of 4.58×106 V/m. (a) What energy in keV is given
to the electron if it is accelerated through 0.562 m? (b) Over what
distance would it have to be accelerated to increase its energy by
58.0 GeV? Draw a diagram and show your parameters and all your
work.
