A cylindrical shell of radius 7.00 cm and length 2.57 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 16.0 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. Required:
a. Use approximate relationships to find thenet charge on the shell.
b. Use approximate relationships to find theelectric field at a point 4.00 cm from the axis, measured radiallyoutward from the midpoint of the shell.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
