Q. 65.0( 1 Vote )

After a good meal at a party you wash your hands and find that you have forgotten to bring your handkerchief. You shake your hands vigorously to remove the water as much as you can. Why is water removed in this process?

Answer :

When we shake our hands after washing them, this gives acceleration to the hand then this acceleration is also imparted to the water molecules, thus the water molecules move away from the hand. This acceleration comes into picture, because of the centripetal force acting on water particles, giving rise to centripetal acceleration.
