Q1. A 1190-N uniform beam is attached to the vertical wall at one end and is supported by a cable at the other end. A 1915-N crate hangs from the far end of the beam. By the data shown in the figure, find (a) the magnitude of the tension in the wire and the magnitudes of the (b) horizontal and (c) vertical components of the force that the wall exerts on the left end of the beam.

Q2. Coherent light with wavelength 546 nm passes through two very narrow slits, and the interference pattern is observed on a screen the distance of 3.00 {rm m} from the slits. The first-order bright fringe is a distance of 4.86 {rm mm} from the center of the central bright fringe.
