A uniform wooden rod (specific gravity = 0.6, diameter = 4 cm and length = 8 m) is immersed in the water and is hinged without friction at point A on the waterline as shown in the figure. A solid spherical ball made of lead (specific gravity = 11.4) is attached to the free end of the rod to keep the assembly in static equilibrium inside the water. For simplicity, assume that the radius of the ball is much smaller than the length of the rod.
Assume density of water = 103 kg/m3 and π = 3.14.
Radius of the ball is _______ cm (round off to 2 decimal places).
Assume density of water = 103 kg/m3 and π = 3.14.

Given
Specific gravity of wooden rod ( S1 ) = 0.6
Diameter of the rod ( D1 ) = 4 cm ⇒ r1 = 2 cm
Length of rod (l ) = 8 m
Specific gravity of spherical ball ( S2 ) = 11.4
Weight of the rod
Weight of the sphere ball
Where,
r1 = radius of rod
r2 = radius of sphere
Buoyant force
r2 = 0.03610 m
r2 = 3.61 cm
Hence, the radius of the ball is 3.61 cm.
