As shown in the figure, the football is in a state of equilibrium under the action of gravity, pulling force and supporting force. The resultant force of gravity mg and supporting force F N It is equal in magnitude and opposite to the pulling force T:
So there is: T= mg cosα, F N =mg?tanα
Answer: The pulling force of the suspension rope on the ball and the support of the wall on the ball The forces are mg cosα and mgtanα respectively.
