In a different configuration, we have a conductor at x = 5 with a surface charge of 10 nC/m2 . Another conductor is occupying the region x=-5 with a surface charge -10 nC/m2 .Find D and E between and outside the two conductors.

a) In an experiment using a copper made conductor, the resistance of the conductor which has a diameter of 0.1045 inches is 75 n. Assume conductivity of a copper as 5.8 X 10' S/m. Find the length of the copper conductor in meters. [1 inch = 0.0254 m]

A coadal cable has a surface charge density of-10 Cim, at the outer conductor and 10 Cim at the inner conductor The inner radius is 2 m, outer Xradius is 6 m and length of this coaxial cable is 100 m. What is the E field inside the inner conductor in between two conductors and outside of the outer conductor (You can leave the expression in terms of permittivity)

Consider a conductor plate carrying a current I as shown in the figure. Current flows in the negative direction. It is also known that a conductor has a charge-carrying density of n with 1 particle carrying a charge q . This conductor plate is then placed on the a region with an external magnetic B field in the z direction . Determine the potential difference across the conductors! State the answer in terms of B, n, q, I, B, and d! (Assume positive charge carrier) *This potential, which is often referred to as the Hall potential V_H, is commonly measured in experiments to determine the properties of a material. However, there are other quantities that are also measured namely the Hall coefficient R_H. In ordinary metals, the relationship between R_H and V_H is as following (equation in figure)
