Answer Key / Explanation : (c) -
(c)
Let 
be the length of the cylinder in water it is in the vertical position and 
be the cross-sectional area of the cylinder. As cylinder is floating so

or 
When the cylinder is tilled through an angle 
, length of cylinder in water 
Weight of water displaced 
Restoring force
