Answer carefully.
What meaning would you give to the capacitance of a single Conductor?
The single conductor can form condenser with the other conductor at infinity. Hence the meaning of storage of charge retains.
Answer carefully:
(a) Two
large conducting spheres carrying charges Q1
and Q2
are brought close to each other. Is the magnitude of electrostatic
force between them exactly given by Q1
Q2/4Ď€
r
2,
where r is
the distance between their centres?
(b) If Coulomb’s law involved 1/r3 dependence (instead of 1/r2), would Gauss’s law be still true?
(c) A small test charge is released at rest at a point in an electrostatic field configuration. Will it travel along the field line passing through that point?
(d) What is the work done by the field of a nucleus in a complete circular orbit of the electron? What if the orbit is elliptical?
(e) We know that electric field is discontinuous across the surface of a charged conductor. Is electric potential also discontinuous there?
(f) What meaning would you give to the capacitance of a single conductor?
(g) Guess a possible reason why water has a much greater dielectric constant (= 80) than say, mica (= 6).
