You are suggested to study NCERT activity 10.5 class 9 science chapter 10 explanation with a conclusion so that you can attempt questions based on the activity 10.5 class 9 science.

Activity 10.5 Class 9 Science

   ·     Take a beaker filled with water.

   ·     Take an iron nail and place it on the surface of the water.

   ·     Observe what happens?

      

Iron nail sinks in water

Observation Activity 10.5 Class 9 Science

The iron nail sinks into the beaker.

Explanation Activity 10.5 Class 9 Science

The gravitational force acts on the nail vertically downward. The weight of the nail is more than the upthrust force or buoyant force, that’s why the nail sinks in water.

The density of an iron nail is more than the density of water so the upthrust of water is less than the weight of the nail so it sinks in water.

Conclusion Activity 10.5 Class 9 Science

This activity shows that the relation between the weight of the object and upthrust is responsible for the floatation of the object.
