A water-alcohol mixture is prepared such that its density is exactly equal to the density of some oil. What would be the shape of a drop of that oil in the given mixture and why?

Explanation

To determine the shape of a drop of oil in a water-alcohol mixture where the density of the mixture is equal to the density of the oil, we can follow these steps:

### Step 1: Understand the Concept of Density
Density is defined as mass per unit volume. When two substances have the same density, they exert equal buoyant forces on each other.

### Step 2: Analyze the Situation
In this scenario, we have a drop of oil that is placed in a water-alcohol mixture. The density of the mixture is equal to the density of the oil.
