The space between two concentric conducting spherical shells of radii b = 250 cm and a = 180 cm is completely filled with a dielectric material that has dielectric strength 6 kV/mm. The capacitance is determine to be 5800 nF. Determine the dielectric constant. Give your answer in the form "a.bc x 10^Yes"
Determine magnitude of the free charge q on the plates of the capacitor when a potential difference of 45 V exists between the terminals of it. Give your answer in the form "a.bc x 10^" micro-Coulomb.
Determine the magnitude of the induced charge q' just inside the surface of the dielectric. Give your answer in the form "a.bc x 10^" C.
What is the magnitude of the electric field at a point midway between the plates of the capacitor? Give your answer in the form "a.bc x 10^" V/m.
What is the maximum voltage (i.e., potential difference) that can be safely applied across the capacitor terminals before it is ruined. Give your answer in the form "a.b" MV.
