Given that the mass of an electron is me= 9.11x 10-31kg and its charge is qe=-1.6 x 10-19C, determine the magnitude and the direction of the acceleration of the electron. ~ b-:'\ V .:: 2~ 4 y.. 10 <j; 2. Two parallel plates (of area .25 m2 each) are separated a distance of .1 mm. A sheet of paper (dielectric constant 4.0) is inserted between the two ~ plates to fill the gap between the plates. These plates are given charges 2JlC and-2JlC respectively. The electric field due to a planar sheet of charge of uniform densityais given by (E=a/ 2 eo),where eo = 8.85 X 10-12 81 a) Determine the electric field between two plates before and after the paper was inserted. b) Determine the surface charge density induced on the surface of the dielectric material....
