A sign hanging in the window of Joe's Diner has a mass of 2 kg. If the supporting strings each make an angle of 45° with the sign and the supporting hooks are at the same height (as shown in the figure below), find the tension (in N) in each string. (Assume that gravity exerts a force of 9.8m N on an object of mass m kg.)
