Two long cylinders of radii 5 cm and 10 cm form a coaxial cylindrical capacitor, the space between them being filled with a dielectric of relative permittivity 6. the inner cylinder carries a charge of 10-8 c m-1 of its length. calculate: -
(a) the value of the electric displacement, field strength, and the polarisation at a
point mid-way between the plates;
(b) the potential difference between the plates;
(c) the densities of the surface charges of the dielectric;
(d) the energy associated with the dielectric in one metre of the capacitor.

neither accurate nor precise.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
