Question

Two conducting spheres of Radius R1 and R2 each have an initial charges of Qi1 and Qi2 respectively. The two spheres are brought together until they make contact. After they are in contact find the ratio of the charge density of sphere 1 to sphere 2. In other words, find Charge density f1/ Charge density f2

Suppose a conducting sphere, radius r2, has a spherical cavity
of radius r1 centered at the sphere's center. At the center of the
sphere is a point charge -4Q. Assuming the conducting sphere has a
net charge +Q determine the electric field,magnitude and direction,
in the following situations:
a) From r = 0 to r = r1.
b) From r = r1 to r = r2.
c) Outside of r = r2
d) find the surface charge density (charge per...

A conducting sphere of radius r1 = 0.32 m
has a total charge of Q = 2.4 μC. A second uncharged
conducting sphere of radius r2 = 0.45 m joins
to the initial by a small conducting wire. In comparison with their
size, the spheres have an enormous distance separating them.
a) What is the total charge on sphere two Q2
after they are connected, in coulombs?
b) What is the surface charge density of the second sphere,
σ2, after...

Three identical metallic conducting spheres carry the following
charges: q11 = +8.20 μC, q22 = +7.80 μC, and q33 = −2.80 μC. The
spheres that carry the charges q11 and q22 are brought into
contact. Then they are separated. After that, one of those two
spheres is brought into contact with the third sphere that carries
the charge q33; those two are then separated as well.
a) What is the final charge on the third sphere?
b)How many excess (or...

There are two identical, positively charged conducting spheres
fixed in space. The spheres are 32.0 cm apart (center to center)
and repel each other with an electrostatic force of F1 = 0.0750 N.
Then, a thin conducting wire connects the spheres, redistributing
the charge on each sphere. When the wire is removed the spheres
still repel but with a force of F2 = 0.100 N. Using this
information, find the initial charge on each sphere, q1 and q2 if
initially...

There are two identical, positively charged conducting spheres
fixed in space. The spheres are 47.8 cm apart (center to center)
and repel each other with an electrostatic force of F1 = 0.0720 N.
Then, a thin conducting wire connects the spheres, redistributing
the charge on each sphere. When the wire is removed the spheres
still repel but with a force of F2 = 0.115 N. Using this
information, find the initial charge on each sphere, q1 and q2 if
initially...

Two identical conducting spheres on insulating stands together
have 6.00 X 1013 excess protons. 4.00 X 1013
electrons are transferred when they come into contact with each
other and then they are separated by 5.00 meters.
a) find the original charge of each sphere
b) determine the electostatic force on each sphere after they
are brought in contact.
c) What distance between the spheres before they are brought
into contact would produce the same force?
d) What mass would the...

A capacitor consisting of two concentric spheres of radius
R1 and R2 = 3.50·R1 has a
capacitance of C = 4.00 picoFarads and is charged to a potential
difference of 68.0 Volts.
If the radius of the outer sphere is increased by a factor of
3.50 while keeping the charge on the plates constant, by what
factor does the stored energy change?

Three identical metallic conducting spheres carry the following
charges: q 1 1 = +8.20 μC, q 2 2 = +8.20 μC, and q 3 3 = −3.60 μC.
The spheres that carry the charges q 1 1 and q 2 2 are brought into
contact. Then they are separated. After that, one of those two
spheres is brought into contact with the third sphere that carries
the charge q 3 3; those two are then separated as well. What is...

There are two identical, positively charged conducting spheres
fixed in space. The spheres are 49.0 cm apart (center to center)
and repel each other with an electrostatic force of F1 = 0.0705 N.
Then, a thin conducting wire connects the spheres, redistributing
the charge on each sphere. When the wire is removed the spheres
still repel but with a force of F2 = 0.115 N. Using this
information, find the initial charge on each sphere, q1 and q2 if
initially...

Two tiny conducting spheres are identical and carry charges of
-19.2C and +71.7C. They are separated by a distance of 2.38 cm. (a)
What is the magnitude of the force that each sphere experiences?
(b) The spheres are brought into contact and then separated to a
distance of 2.38 cm. Determine the magnitude of the force that each
sphere now experiences.
