Draw and FBD of a rubber stopper (mass) in circular horizontal motion. Be realistic here: Is the tension force on the stopper truly horizontal?
This question is from an experiment where a rubber stopper is tied to a string and swung horizontally. When the question says "Be realistic here," it means that the rubber stopper is being swung horizontally but at a slight angle (such as 10 degrees) below the horizontal.
The Attempt at a Solution
I know that there's going to be a Fg downwards on the stopper, and a Force of tension going from the stopper to the centre of rotation, but I'm not sure about other forces such as Fc and which direction it would be going.
