Expert Answer

Step 1

The water remains in the pail and does not spill due to the inertia of the water. The tendency of the water is to move along the straight line (as per the Newton’s First law of motion) but the pail pulls the water inwards in a circle.

 

Step 2

Due to the circular motion, the centrifugal force develops which is responsible for the inward pull of the water towards the centre of the whirl.

Step 3

Here, due to the centrifugal force an acceleration is produced (radial). If the acceleration produced ex...
