An irregular neutral conductor has a hollow cavity inside of it and is insulated from its surroundings. an excess charge of 16.0 nc is sprayed onto this conductor. part a: find the charge on the inner surface of the conductor.
part b: find the charge on the outer surface of the conductor.
part c: without touching the conductor, a charge of -10.0 nc is inserted into the cavity through a small hole in the conductor. find the charge on the inner surface of the conductor in this case.
part d: find the charge on the outer surface of the conductor in this case.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
