The reading of a spring balance when a b...

The reading of a spring balance when a block is suspended from it in air is 60 N. This reading is changed to 40 N when the block is submerged in water. The relative density of the block is:

A

`3`

B

`2`

C

`6`

D

`3//2`

Text Solution

Verified by Experts

The correct Answer is:
A

Specific gravity or relative density `1=("weight in air")/("change of weight in water")=(60)/(20)=3`
