Question

Choose the correct statement among the following

• A. The upthrust on a floating body is in upwards direction and is equal to the weight of the liquid displaced
• B. The upthrust is directly proportional to the density of the liquid in which the solid is immersed
• C. The upthrust is directly proportional to the volume of the fluid displaced by a solid
• D. The total lateral pressure acting on an immersed object on one side is equal and in same direction to the total lateral pressure acting on the other side

Answer 1

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

The correct options are
A The upthrust on a floating body is in upwards direction and is equal to the weight of the liquid displaced
B The upthrust is directly proportional to the density of the liquid in which the solid is immersed
C The upthrust is directly proportional to the volume of the fluid displaced by a solid

The upthrust acts on the body in upward direction at the center of buoyancy.

Upthrust is equal to the weight of liquid displaced by object and weight of liquid will depend on its density.

Upthrust is $F=V\rho g$ ,where V is the volume of liquid displaced and $\rho$ is the density of fluid.

The total lateral pressure acting on an immersed object on one side is equal and in opposite direction to the total lateral pressure acting on the other side.
