! Research ! The condition of static equilibrium tells us that the sum of the x-components of the three forces acting on the ball must equal zero and the sum of y-components of these forces must equal zero ! The sum of the x-components of the forces is T is magnitude of the string tension ) is the angle of the string relative to the vertical
