A capacitor is formed of two concentric spherical conducting shells ofradii a and b . If the medium between the spherical shells has a dielectric constant K_(1) from radius a to r and K_(2) from radius r to b , find the capacitance of such a spherical capacitor shown in figure.

Capacitors P and Q have identical cross sectional areas A and separation d. The space between the capacitors is filled with a dielectric of dielectric constant epsilon_(r) as shown in the figure . Calculate the capacitance of capacitors P and Q .

(a) Find the capacitance of spherical capacitor having concentric shells of radii a a and b (bgta) . The space between the shells is completely filled by a dielectric of constant k . (b) Find the capacitance if dielectric is filled upto an intermediate radius c(a lt c lt b) between the shells.

A metallic spherical shell of radius r_1 is surrounded by another concentric metallic spherical shell of radius r_2 . The space between the two shells is filled with a dielectric of dielectric constant K. If a charge Q is given to the inner shell, the charge appearing on the outer surface of the outer shell is
