Photoelectric effect experiments are performed using three different metal plates p, q and r having work functions ip = 2.0 eV, iq = 2.5 eV and ir = 3.0 eV, respectively. A light beam containing wavelengths of 550 nm, 450 nm and 350 nm with equal intensities illuminates each of the plates. The correct I-V graph for the experiment is?? Consider a branch of the hyperbola x^2 - 2y^2 - 22 x - 42 y - 6 = 0 with vertex at the point A. Let B be one of the end points of its latus rectum. If C is the focus of the hyperbola nearest to the point A, then the area of the triangle ABC is?
