2) The functional dependence of the electric field from some highly symmetric shapes can be determined rather straightforwardly from dimensional analysis. Given that the electric field is defined by the equation F=qE and the force on a point charge q2 from a charge qi a distance r away is |F| = kla:||92| A) Find the dimensionality of the Coulomb constant k and the electric field E in terms of the basic dimensions, M, L, T, and Q. Show your work. B) For a long uniform line of charge, we know neither the total charge on the line nor its length, only the 'charge per unit length', A, with units of Coulomb/meter. Assuming that the dependence of the E-field produced by that line as a function of the (perpendicular) distance d from the line will look something like akλ E= = dn where a is a dimensionless constant. Use dimensional analysis to find the value of n. C) For a large flat uniform sheet of charge, we know neither the total charge on the sheet nor its area, only the charge per unit area, o, with units of Coulomb/meter. Assuming that the dependence of the E-field produced by that line as a function of the (perpendicular) distance d from the sheet will look something like D) E = aka dn where a is a dimensionless constant. Use dimensional analysis to find the value of n.
