A sphere of mass 3.1 ✕ 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes a constant angle of 33° with the vertical. What is the magnitude of the push? What is the tension in the cord?
Thank you for the opportunity to help you with your question!
The push of the sphere raises it and tension is produced in the cord.
The tension in cord = mgcos¢°
Where ¢ is the angle made
So tension T = 2.54x 10^-3 N
Since the tension produced is due to the force of the push.
The magnitude of push = 2.54x 10^-3 N.
