Question

Suppose that you had a cylinder that was made so that it was half wood and half lead by volume. Think of this as two identically shaped cylinders glued end to end. If you place it in a deep enough pan of water it will sink. Compare the buoyant force on this composite cylinder to what it would have been if both parts were made of lead.

A. The bouyant force on the composite cylinder is larger than that on the all lead cylinder.

B. The bouyant force on the composite cylinder is smaller than that on the all lead cylinder.

C. The bouyant forces are the same.

Explanation / Answer

B. The bouyant force on the composite cylinder is smaller than that on the all lead cylinder.

because, Buoyant force = weight of the fluid dispalced

= rho_fluid*V_submenrged*g

so, in both cases the volume of submerged cyllinder is same. so, Buoynat force is alsi same.
