Two concentric charged metal spherical shells are held fixed in space. All other charges are very far away. The smaller shell (call it shell A) has an inner diameter of 5 [cm], an outer diameter of 10 [cm], and a total charge of +10 [nC]. The larger shell (call is shell B) has an inner diameter of 25 [cm], an outer diameter of 30 [cm], and a total charge of +10 [nC]. Find the electric field (Both magnitude and direction)...

A solid sphere of radius (a = 3.00 cm) is concentric with a spherical conducting shell of inner radius (b = 2.00 cm) and outer radius (c = 2.40 cm) . The space between the sphere and the inner surface of the shell is empty. The sphere, made of a dielectric, has a net uniform charge of (q1 = +5 micro Coulombs). The shell has a net charge (q2 = - q1) . 1) What is the magnitude of the...

Two concentric spherical shells of diameter 13.6 cm and 26.0 cm are used to form a spherical capacitor. The charges on the inner and outer shells are −5.00 µC and +5.00 µC, respectively. (a) Determine the potential difference from the inner to the outer shell. Use the fact that the magnitude of the electric field at a distance r from the center of the inner shell is given by E = kQ/ r2 , where k is Coulomb's constant and...

A spherical capacitor has a spherical inner plate with radius a
and outer plate with radius b. The charge on the inner plate is +Q
and on the outer plate it is -Q. We have filled a cone shaped
region of angle θ (0 ≤ θ ≤ π) with a dielectric with constant κ.
The dielectric fills the entire volume between the two spheres
inside the cone. You may neglect any fringing effects between the
dielectric and the vacuum (dielectric...

In a coaxial cylinder (CC) conductivity cell with the inner electrode electrified and a dielectric liquid between them, how is the fringe field effect dealt with? Is the effect as severe as in a parallel plate cell and if a guard electrode is used where is it placed? Would really appreciate a drawing of the ideal guard position in a CC cell. Thank you.

Suppose that we have an axon that is 10 cm long, with an inner radius r1 of 1 μm and outer radius r2 = r1+ 1nm = 1 μm + 1nm. In this exercise, you may use a dielectric constant for cellular fluid of κ = 3. Write an expression for the magnitude of the Electric Field, “E” outside (at an arbitrary radius r) for a uniformly charged cylinder of length “l” with charge “q”: This cylinder is in a...
