The electric field must be zero inside a conductor in electrostatic equilibrium, but not inside an insulator. it turns out thatwe can still apply gaussās law to a_ gaussian su_rface that is entirely within an insulator by replacing the right-hand side ofgaussās law, q5160, with qinie, when: 5 is the permittivity of the material- (technically, 60 is called the vacuumpermittivity.) suppose a long, straight wire with linear charge density 250 nc/ m is covered with insulation whosepermittivity is 2,550,. what is the electric ļ¬eld strength at a point inside the insulation that is 15 mm from the axis of thewire?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
