he drawing shows a square, each side of which has a length of L = 0.250 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = -3.00 x

An oil slick (n = 1.22) on water (n = 1.33) has a uniform thickness of 517 nm. It is illuminated by white light (400-700 nm) at normal incidence. In the reflected light, find the first wavelength that is a) enhanced and b) missing.
