Banao on this and if still not able to solve then you must understand . It may not be an easy qus 

for many students as 

1) Recognition of centripetal force can be a problem

2)Relating this force with force exerted by liquid

3)Identification of force exerted by liquid like what kind of force, reason of force etc

4)Final & most important thing ; value of radius . As many students can think its equal to length. Concept of center of mass may not strike.

I hope you must understand the solution and things will be easier now. Try to learn and next time , do it yourself.
