Four wires, all of them horizontal, are attached to the top of a telegraph pole as shown in the plan view on the right. The pole is in equilibrium and tensions in the wires are as shown. (i) Using perpendicular directions as shown in the diagram, show that the force of 60 N may be written as 15.5 -58.0 N (to 3 significant figures). (ii) Find Tin both component form and magnitude and direction form. 40 (iii) The force Tis changed to 35 N. Show that there is now a resultant force on the pole and find its magnitude and direction. 450 www.paper24.org
