Answer #1

A total charge of 20.0 nC is distributed uniformly through an
insulating sphere with a radius of 6.00 cm. The total electric flux
(in N m2/C) through a concentric sphere with a radius of
3.00 cm is:
K = 9 x 10+9 N.m2.C-2 ,
ε0 = 8.85 x 10-12

sphere. Plot the electric potential V vs. the distance r from the
center of the sphere for 0 < r < 2R

A uniformly charged insulating sphere
(R1 = 3.0 cm) is charged to
QI = 50 nC. It is concentric within a
charged conducting shell (inner radius
R2 = 5.0 cm, outer radius
R3 = 5.2 cm) that is charged
to QC = 200 nC. The insulating sphere is
not connected to the conducting shell, and the conductors are
separated by air. (Note: The figure is not to scale.)
In which region(s) is the electric field zero, if any?
(b) Find...

Charge Q is distributed uniformly throughout the volume of an
insulating sphere that has radius R. What is the potential
difference between the center of the sphere and the surface of the

(physics 2)
Charge Q is distributed uniformly over the volume of an insulating
sphere of radius R. What is the potential difference between the
center of the sphere and the surface of the sphere?

5. Consider a system consisting of an insulating sphere of
radius a, with total charge Q uniformly spread throughout its
volume, surrounded by a conducting spherical inner radius b and
outer radius c, having a total charge of -3Q. (a) How much charge
is on each surface of the spherical conducting shell? (b) Find the
electric potential for all r, assuming v=0 at infinity.

Charge Q=+ 3.00 μC is distributed uniformly over the volume of
an insulating sphere that has radius R = 6.00 cm .What is the
potential difference between the center of the sphere and the
surface of the sphere?

A thin aluminum sphere of radius 25 cm has a charge of Q=150 nC
uniformly distributed on its surface.
a) Assuming that the center of the sphere is at r=0, find
expressions for the electric field for all regions of interest
(r<R, and R>r), and make a plot of the electric field
strength as a function of r.
b) Find expressions for the electric potential for all regions
