Question

A body is just floating such that it is completely immersed on the surface of a liquid. The density of the body is same as that of the liquid. The body is slightly pushed down upto small distance. What will happen to the body.

• A. It will slowly come back to its earlier position
• B. It will remain floating at the same position where it is left
• C. It will sink
• D. It will come out violently

Answer 1

The correct option is B It will remain floating at the same position where it is left

Given,

Body completely immersed on the surface of a liquid.

It means, buoyancy force = weight of the body

And, while pushing quasi-statically body, Body move without acceleration.

When the body left after a certain distance there is no net acceleration on the body.

Hence, it will remain there where it is left inside the liquid.
