Solution

The correct option is C


l = length of cylinder

A = Area of crossection of cylinder

mg = (A) (l) (ρ) (g)

m = Alρ

When cylinder is tilted through an angle

length of cylinder in water = 1cos θ

wt of water displaced = lcos θA ρ g

restoring force = lAρgcos θlAρg

= lAρg(1cos θ1)=mg(1cos θ1)
