A lump of ice floats in water as shown in the figure .

Which of the following statements is correct ?

A

The lump of ice floats because the area of its lower surface is larger than the area of its upper surface .

B

The pressure difference between the lower and the upper surfaces of the lump of ice gives rise to an upthrust equal to its weight .

C

The ice has a greater density than water .

D

The mass of water displaced by ice is equal to the upthrust .

Text Solution

Verified by Experts

The correct Answer is:
B
Upthrust on the lump of ice by the water is equal to the weight of the lump of ice.
Upthrust is developed by the pressure difference between the lower and the upper sufaces of the lump of ice.
