9. A 3kg sign hangs in a hall in the Physics  Department . What is the tensile strength necessary for the cord that is used to hang the sign?

mass = m = 3 kgIt is basically that there are 2 cords attached hence the weight will beequally balancedTherefore the vertical component of the tensile force must be 1.5kg.2T sin45 = 3 x9.8...
