The Attempt at a Solution

My question is about the perspective. The picture on my book is like this:
___________|---0.5m---\_/
=====================


So should I draw the free body diagram from this perspective, with the weight by the Earth on the cup pointing down, or from the top down perspective where I can see the friction force?

You can go either way. Show forces into the page as an X in a circle.
The friction force would be toward the center of the turntable, so would look the same in either view.
