I have a ball. It is attached to a wall by a horizontal string to the left. it is attached to the ceiling by another string at an angle theta from the vertical to the right.
The ball is not moving. So I worked out that the tension in the upper string is w/(cos theta) , where w is weight. Is this correct before I go on?
