True or False? A perfect electric dipole False
feels a net force in a uniform electric field.
True or False? Electric field lines that are False
spaced close together imply a weak
electric field
true or false? the electric force between True
two charges is inversely proportional to the
square of the distance separating them.
I bring a positively charged rod near an Induction
uncharged metal sphere, but not touching.
I then group the metal sphere, leaving the
sphere with a net charge. This is called
charging by
True or False? The net outward electric flux -x
passing through any closed surface is
equal to the net charge enclosed by the
surface divided by a constant.
True or False? The net outward electric flux True
passing through any closed surface is
equal to the net charge enclosed by the
surface divided by a constant.
Suppose I have a spherical insulating shell ?
with inner radius r and outer radius R. The
shell has a uniformly distributed charge of
+Q. What is the charge density on my shell
Suppose I have a conducting sphere of ?
radius R. I place a net charge of +Q on the
sphere. What is the charge density inside
the sphere?
True or False? The electric field produced True
by a uniform, infinite plane of charge does
not depend on the distance from the plane.
True
True or False? The electric field is zero True

True or False? If I have a constant electric True
potential in some region of space, that
implies the electric field is zero.
True or False? If I have a constant electric False
field in some region of space, that implies
the electric potential is zero.
True or False? The surfaces of equal True
potential around an infinite charged plane
are parallel to the plane (i.e. the surfaces
never intersect the charged plane).
Suppose I center a conducting sphere of E=0
charge (radius R, total charge +Q) at the
origin. How much energy would it take to
move a point charge (total charge +q) from
the surface of the sphere (r = R) to the
center of the sphere (r = 0)?
Suppose a capacitor of capacitance C is 4E
connected to a battery with voltage V. We
measure the energy stored in the capacitor
to be E. If we were to now double the
voltage of the battery (keeping C the
same), what is the new energy stored in the
capacitor?
Suppose I build a parallel plate capacitor 2Q
with plate area A and plate separation D. I
hook it up across a battery of voltage V and
charge it up to some final charge Q. If I
were to double the plate area (keeping
everything else constant), what is the new
charge on the capacitor?
Suppose I hook ten capacitors (each of C/10
capacitance C) in series. What is the net
capacitance of the circuit?
True or False? When a dielectric material is True
inserted in between the plates of a
parallel-plate capacitor, the electric field
between the plates is weakened by the
dielectric.
True or False? The current passing through True
some surface is equal to the flux of the
current density through the surface.
Suppose I have a resistor of some R
resistance R. If I were to double the length
and double the cross-sectional area of the
resistor, what is the new resistance?
Suppose I hook ten resistors (each of R/10
resistance R) in parallel. What is the net
resistance of the circuit?
