1. A sample of germanium shows no Hall effect. If the mobility of electrons in germanium is 3500 cm cube/v. see and that of holes is 1400cm cube/v. see. What fraction of the current in the sample is carried by the electrons?
The dielectric constant of sulphur is 3.4. Assuming a cubic lattice for its structure, calculate the electric polarisibility of sulphur. Given for sulphur, density = 2.07gm/cc, At. Wt. = 32.07
