a framed picture of weight 15N is hung on a wall, using a piece of string. The ends of the string are tied to two points, 0.60 m apart on the same horizontal level, on the back of the picture.Find the tension in the string if the string is 1.0m long
make two right triangles.
Consider one side.
but sinTheta=1/2 weight/tension
