(a) 5 × (b) 10-6s (c) 5 hr 10 ogeheous (d) 10 hr (e) 15 hr lds shown in Figure 5.19 are near a dielectric-dielectric boundary but on opposite sides ns are correct? Assume that the boundary is charge free and that ε? ε' ch of the following statements are incorrect? (a) The el Nonpolar molecules have no permanent dipoles. (d) In a linear dielectric, P varies linearly with E. uctivities of conductors and insulators vary with temperature and frequency. tor is an equipotential body in steady state, and E is always tangential to the conductor. s ue The electric conditions (charge and potential) inside and outside an electric screening are completely independent of one another.
