Question

Calculate the buoyant force that would be exerted on a wood cylinder if you held it under water. How much force must you exert to keep it submerged?

Answer 1

Answer #1

Suppose we held the cylinder in water by applying force F downward.

Then Bouyant force = dVg where d is density of water and V is volume of cylinder.

Force exerted by me = mg - bouyant force

= mg - dVg
