Use the triangle.
tan41=horizonal push/mg
Then,
cos41=mg/tension
A sphere of mass 3.3 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes an angle of 41° with the vertical when at rest
(a) Find the magnitude of that push.
(b) Find the tension in the cord.
