Question

A solid floats in a liquid in a partially dipped position.
(a) The solid exerts a force equal to its weight on the liquid.
(b) The liquid exerts a force of buoyancy on the solid which is equal to the weight of the solid.

(c) The weight of the displaced liquid equals the weight of the solid.
(d) The weight of the dipped part of the solid is equal to the weight of the displaced liquid.

Answer 1

(a) The solid exerts a force equal to its weight on the liquid.

(b) The liquid exerts a force of buoyancy on the solid which is equal to the weight of the solid.

(c) The weight of the displaced liquid equals the weight of the solid.

EXPLANATION:  

(a) The weight acts downward so the floating solid will exert a force equal to its weight on the liquid. 

(b) In the case of floating solid the force of buoyancy is equal to the weight of the solid, that is why it floats. 

(c) The weight of the displaced liquid is equal to the force of buoyancy which is equal to the weight of the solid. Archimedes principle. 

(d) is not true because it is not according to the explanation (c) above.
