Answercarefully:(a) Twolarge conducting spheres carrying charges Q1and Q2are brought close to each other. Is the magnitude of electrostaticforce between them exactly given by Q1Q2/4πr2,where r isthe distance between their centres?(b) IfCoulomb’s law involved 1/r3dependence (instead of 1/r2),would Gauss’s law be still true?(c) A smalltest charge is released at rest at a point in an electrostatic fieldconfiguration. Will it travel along the field line passing throughthat point?(d) What isthe work done by the field of a nucleus in a complete circular orbitof the electron? What if the orbit is elliptical?(e) We knowthat electric field is discontinuous across the surface of a chargedconductor. Is electric potential also discontinuous there?(f) Whatmeaning would you give to the capacitance of a single conductor?(g) Guess apossible reason why water has a much greater dielectric constant (=80) than say, mica (= 6).
