A beaker full of water is suspended from a spring balance. Will the reading of the balance change:
If a cork is placed in water ?
If a piece of heavy metal is placed in it ?
Give the reasone for your answer

Text Solution

The correct Answer is:
The reading of spring balance will not change if a cork is placed reading of spring balance will change if a piece of heavy metal is placed in water because heavy metal, being denser than water, sinks in water
