A painting hangs at rest from a string. A second, horizontal string is knotted to the first pulling it to the right, as shown below. The top section of the first string is at an angle of 25 degrees to the vertical. The tension in the horizontal string is 0.8N. The magnitude of the acceleration due to gravity is g = 9.8 ms-2 What are 3 forces acting on the knot? Draw a forge diagram to represent them and indicate their directions by marking sizes of relevant angles.
