Question

The weight of a body felt in tap water and salty water are WA and WB respectively, then

1 point

(a) WA =WB

(b) WA > WB

(c) WA < WB

(d) WB = 2WA.​

Answer 1

Answer:

As density of salty water is more than density of tap water .

It will exert a greater buoyant force (upthrust) and ,

So,Wt is greater than Ws.

Principles bqsed;: Archimedes principles

Answer 2

The correct option will be B, i.e. WA>WB.

• The weight of the body is very much dependent on the upthrust it experiences from the liquid.
• Since the density of salty water is higher than the density of tap water, it will give a higher upthrust to the body.
• Since salty water gives a higher upthrust, thus the weight of the body felt in salty water will be less than that in tap water.
