(a)Will the electric field strength between two parallel conducting plates exceed the breakdown strength of dry air, which is 3.00 × 106 V/m , if the plates are separated by 2.00 mm and a potential difference of 5.0 × 103 V isapplied? (b) How close together can the plates be with this applied voltage?

In one of the classic nuclear physics experiments at the beginning of the 20th century, an alpha particle was accelerated towards a gold nucleus and its path was substantially deflected by the Coulomb interaction. If the initial kinetic energy of the doubly charged alpha nucleus was 5.17 MeV, how close to the gold nucleus (79 protons) could it come before being turned around? (m)

(8) Is the electric field always zero inside a conductor? Explain.

How close together can two parallel conducting plates, with a potential difference of 5.0x10³ V between them, be before the breakdown strength for air (3.0x106 V/m) is exceeded?

(a) Calculate the relative dielectric constant of a SrTiO3 crystal plate, which, when insertedin a parallel plate condenser of area 12 mm x 11 mm and distance of separation of 0.5 mm,gives a capacitance of 1.6x10-7 F.(i) If a SrTiO3 crystal plate with 35% porosity is inserted in that similar parallel platecapacitor, what would be the change in capacitance value? Does it increases ordecreases? Why?(ii) If we replace the porous SrTiO3 crystal plate with a BaTiO3 crystal plate having asimilar 35% porosity, while the “relative permittivity (r)” is exactly similar to theSrTiO3 crystal plate in part (i)what is the change in the capacitance value of thecapacitor?
