11. A rod of mass ' ' and length hinged at end can rotate smoothly in vertical plane about horizontal axis passing through . It is released from a horizontal position as shown in the figure and strikes a block of mass M kept vertically below at distance on a smooth horizontal surface. The block after collision moves on the smooth vertical circular track of diameter such that the force exerted by the circular track on the block at point is on third of its weight. If the rod after collision rotates through an angle from the horizontal, fin the ratio of masses . 12. A plank of mass is placed over smooth triangular wedge with angle of inclination . Block of mass is connected to the plank by massless string. A cylinder of mass and radius is

where α and λ0 are constants. Find the passband Δλ of this light filter, that is the band at whose edges the attenuation of light is times that at the wavelength λ0. The coefficient of reflection from the surfaces of the light filter is assumed to be the same at all wavelengths.
