Question

A wooden block and iron block of same volume are kept in pot containing water. which one experiences more up thrust?
a. Iron block
b. Wooden block
c. Depends upon temperature
d. Depends upon pressure​

Answer 1

In the first situation, when B is placed over A weight of B = ρ

B

Vg

When it falls down in water,

Apparent loss in weight = weight in air - weight in water

= ρ

B

Vg−ρ

L

Vg

Since, according to the given condition, H increases and L decreases, therefore this apparent loss in weight should be negative.

Therefore, ρ

B

<ρ

L

Answer 2

Answer:

d. depends upon pressure

this is the correct answer
