Question

6. The least value of apparent weight of a body in a fluid is
(a) >0
(b) =0 (c) <0 d) depends on the density of solid and fluid​

Answer 1

Answer is Option C

<0 is correct option

Answer 2

Answer:

(b)=0

Explanation:

First of all,option 3 cannot be the answer because if weight of body is<0,it would mean that the body has negative mass,which is not possible.

Now,min. apparent weight will be 0 and such a case is possible when the density of the body is equal to density of the fluid in which it is submerged.

In such a case, gravitational force acting on the body in downward direction would be equal to buoyant force acting in upward direction.

i.e. Fb = mg

As such,the body will float partially submerged in the fluid and the apparent weight would be 0.

It was my first time answering any question but I hope you understood it well.

THANKS!!!

HAVE A GREAT DAY!!!
