Activity 10.7 Class 9 Science

   ·     Take a piece of stone and tie it to one end of a rubber string or a spring balance.

   ·     Suspend the stone by holding the balance of the string.

   ·     Note the elongation of the string or the reading on  the spring balance due to the weight of the stone.

   ·     Now slowly dip the stone in the water in a container.

   ·     Observe what happens to the elongation of the string or the reading on the balance.

      

Observation Activity 10.7 Class 9 Science

When the stone is dipped in the water, the elongation or reading in the spring balance decreases.

Explanation Activity 10.7 Class 9 Science

When the stone is tied with a string or spring balance, elongation is produced due to the weight of the stone. 

As the stone is dipped into the water, the elongation decreases, or the reading in the spring balance decreases.

This happens because an upward force is exerted on the stone. This upward force is an upthrust or buoyant force.

Conclusion Activity 10.7 Class 9 Science

This activity shows that the weight of an object in water is less than that of in the air.
