The drawing shows an elastic cord attatched to two back teeth and stretched across a front tooth. The purpose of the arrangement is to apply a force to the front tooth. If the tension in the cord is 1.2N what are the magnitude and direction of the force applied to the front tooth?
(The drawing is of the top of the mouth with and angle of 66 degrees split into to so 33 degrees and 33 degrees)
