A right circular cylinder has radius R and length L. and a nonuniform volume charge density p(p). If the z axis is chosen to coincide with the axis of the cylinder, the charge density is p(p) - p{z2) = p(z, z) = .p_0 + beta_ z. This means that the charge density varies linearly along the length of the cylinder. Find the force on a point charge q placed at the center of the cylinder. (Adapted from Reitz. Milford, and...
1- A conducting ring of resistance R and radius l is placed in external magnetic field. Determine the charge which will pass through the ring after we give it the shape of 8? Assume that the radius of the top ring is twice smaller that the one of the bottom ring. 2- A conducting rod of length l = 10 cm is moving in external magnetic field B = 0.1 T which makes an angle α = 60◦ with the...
2. (30 points) A very long, straight, solid copper cylinder of radius R (>2R) is oriented with its axis along e z-direction. The cylinder carries a current whose current density is j(r), where r is the radial distance from the cylinder axis. The current density, although symmetric about the cylinder axis, is not constant but varies with r according to 31o a) (10) Obtain an expression for the current /(in terms of Jo, r and R) flowing in a circular...
Hello, I'm looking for some help with a physics problem.
We have a very long conducting cylinder/wire with a radius of R0
and length of L, where R0 is much smaller than L, possesses a
uniform volume with a positive charge density pe C/m^3. Determine
the electric field at points A) outside the cylinder and inside the
cylinder. Do this for points far from the ends. Write out the steps
and details for creating the formula. b) If R0 =...
4) A very LONG hollow cylindrical conducting shell (in electrostatic equilibrium) has an inner radius R1 and an outer radius R2 with a total charge -5Q distributed uniformly on its surfaces. Asume the length of the hollow conducting cylinder is "L" and L>R1 and L>> R2 The inside of the hollow cylindrical conducting shell (r < R1) is filled with nonconducting gel with a total charge QGEL distributed as ρ-Po*r' ( where po through out the N'L.Rİ volume a) Find...
please answer question 8-13
This is the prior information: Nerve impulses are electrical
currents in the form of “ionic flows.” Therefore the electrical
properties of the axon are important to understand in order to
understand the flow of electrical impulses. In this test, you will
explore the capacitance and resistivity of an axon of a nerve cell.
For this test, the axon will be treated as a CYLINDER of arbitrary
length “L” and radius “a” that is filled with a...

The resistor-capacitor network model we developed in Lecture
(see figure below where it is shown only for the myelinated case)
for the transmission of signals in nerve axons can actually be
applied to both unmyelinated and myelinated nerve cells to estimate
the propagation speed of a nerve impulse. In the unmyelinated case
the 6-7 nm thick plasma membrane (the lipid bilayer) acts both as a
(very thin) dielectric layer forming a capacitor between the inside
of the axon and the...
