Abeam of green light illuminates a thin film of oil (noil = 1.47). the thin film is deposited on an opaque surface. in all cases, consider only the reflections at the boundaries with oil. the indices of refraction are: nair = 1, nglass = 1.55 and nwater = 1.34. in which case is green light stringly refelected off the thin film of oil?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

Three resistors are connected in series across a 15-v power supply. if the potential drops across resistors 1 and 2 are 4.1 volts and 3.1 volts, what is the exact potential drop (in volts) across resistor 3?
