AI Generated Solution

To solve the problem, we need to determine the normal force required to separate the two glass plates when a drop of water of volume \( V \) is pressed between them, spreading over an area \( A \) with surface tension \( T \). ### Step-by-Step Solution: 1. **Understanding Surface Tension**: Surface tension \( T \) is defined as the force per unit length acting along the surface of a liquid. It causes the liquid to minimize its surface area. 2. **Relating Volume, Area, and Height**: ...
