Question

If water in one flask and castor oil in other are violently shaken and kept on a table, which will come to rest earlier?

Short/Brief Note

Solution

Castor oil will come to rest more quickly because it has a greater coefficient of viscosity than water.

Castor oil has a higher viscosity than water. It will therefore, lose kinetic energy and come to rest faster than water.
