Consider two concentric spherical shells--one conducting and one non-conducting. The conducting spherical shell has radius 3 cm and total charge of -7 nC, while the non-conducting spherical shell, which is outside the conducting shell, has inner radius 8 cm, outer radius 13 cm, and total charge 7 nC. Determine how strong the electric field is, in kV/m, 12 cm from the center of the conducting shell. Hint: Use Gauss's Law.

Figure shows two concentric and infinitely long dielectric cylindrical shells with dielectric constants & is given by ɛ, = ɛ,- while the outer shell is non-constant and is ɛ, = ɛ, -. 7. ɛ,. The dielectric constant of the inner shell is constant and An infinite and line charge with density p, is placed at the center and along the common axis of the shells. Find a) D everywhere b) E everywhere c) Volume charge density of bound charge in both dielectric layers. a E2 PL 13

A semi-circular conducting body with radius a moves with constant velocity u = 10 (m/s) over a constant magnetic flux density B = â₂5. If the induced voltage on the body given below is -10 (V), calculate a . X ). y

A spherical conductor with a radius of 5 cm is given a potential of 5 volts. A spherical shell with a radius of 10 cm is placed at the center of a spherical conductor and is given a potential of 2 volts. Find the potential at point P which is 10 cm from the center of the sphere.
