Two concentric spherical shells of diameter 13.6 cm and 29.0 cm are used to form a spherical capacitor. The charges on the inner and outer shells are −9.00 µC and +9.00 µC, respectively. (a) Determine the potential difference from the inner to the outer shell. Use the fact that the magnitude of the electric field at a distance r from the center of the inner shell is given by E = KQ/r2, where K is Coulomb's constant and Q is...

A viscometer is an instrument for measuring the viscosity of a fluid. In a simple form, it consists of two concentric cylinders, with the outer cylinder fixed and the inner cylinder free to rotate. The space between the two cylinders is filled with the fluid in question, and the torque required to rotate the inner cylinder at a constant speed is measured. One such device consists of two 21.0-cm long cylinders, one 15 cm in diameter and the other 15.4...

Two concentric charged metal spherical shells are held fixed in space. All other charges are very far away. The smaller shell (call it shell A) has an inner diameter of 5 [cm], an outer diameter of 10 [cm], and a total charge of +10 [nC]. The larger shell (call is shell B) has an inner diameter of 25 [cm], an outer diameter of 30 [cm], and a total charge of +10 [nC]. Find the electric field (Both magnitude and direction)...
