I am being asked to find the FBFD for the ball in this diagram
the black weight on the horizontal rod is just there to prevent the ball from wobbling around when being rotated the arrows are meant to show the motion of everything ( both clockwise ). the vertical rod rotates and depending on how fast its rotated, the string + ball either move up or down ( i forgot to include the theta )
but im just not sure whether the pink arrow would be a normal centripetal force, or the tension force in the x-axis.
the problem also asks how the speed of the ball is related to its rotational period and the lengths (of the string) and radius in the figure, and how the balls acceleration is related to those quantities. i'm honestly not certain at all how to figure out this question so any help/tips towards the right direction would greatly be appreciated, thanks!
