The movement of a fluid during convection is a circular/oval motion since the fluid at the top sinks and the fluid at the bottom rises.
Hope this helps :)
To develop this problem it is necessary to apply the concepts given in the balance of forces for the tangential force and the centripetal force. An easy way to detail this problem is through a free body diagram that describes the behavior of the body and the forces to which it is subject.
PART A) Normal Force.
![F_n = \frac{mv^2}{r}](https://tex.z-dn.net/?f=F_n%20%3D%20%5Cfrac%7Bmv%5E2%7D%7Br%7D)

Here,
Normal reaction of the ring is N and velocity of the ring is v

![-mgsin\theta = ma_t](https://tex.z-dn.net/?f=-mgsin%5Ctheta%20%3D%20ma_t)
![-W sin\theta = \frac{W}{g} a_t](https://tex.z-dn.net/?f=-W%20sin%5Ctheta%20%3D%20%5Cfrac%7BW%7D%7Bg%7D%20a_t)
