QUESTION:

Problem 66P

Consider two identical small glass balls dropped into two identical containers, one filled with water and the other with oil. Which ball will reach the bottom of the container first? Why?

ANSWER:

Solution 66P

Step 1

In this problem, we are keeping water and oil in two identical containers and we are dropping a glass ball in each container. We have to find out which ball will reach the bottom of the container first.

Here, viscosity plays a major role in defining the speed of the glass balls in different media.

Viscosity can be defined as the extent to which a fluid resists a tendency to flow.
