Question

A slid floats in a liquid in a partially dipped position.

• A. The solid exerts a force equal to its weight on the liquid
• B. The weight of the displaced liquid equals the weight of the solid
• C. The liquid exerts a force of buoyancy on the solid which is equal to 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

Answer: (A), (B), (C)

The solid exerts a force equal to its weight on the liquid
The weight of the displaced liquid equals the weight of the solid
The liquid exerts a force of buoyancy on the solid which is equal to the weight of the solid

The force that solid exerts on liquid is its weight. Hence option A is correct.

Since the solid is stationary, the weight of solid is equal to the force exerted on it by liquid.

According to Archimedes' Principle, the buoyant force acting upwards on the solid is equal to the weight of the liquid displaced. Hence option B and C are correct.
