The correct Answer is:
To solve the question, we need to analyze the situation of two glass plates placed close to each other in water. ### Step-by-Step Solution: 1. **Understanding the Setup**: We have two glass plates that are positioned very close to each other and submerged in water. 2. **Identify the Forces at Play**: When two surfaces (in this case, glass plates) are in contact with a fluid (water), we need to consider the forces acting between the plates and the fluid. 3. **Cohesive and Adhesive Forces**: - **Cohesive Forces** are the intermolecular forces that hold the molecules of the fluid (water) together. - **Adhesive Forces** are the intermolecular forces that act between the molecules of the fluid and the surfaces of the glass plates. 4. **Effect of Adhesive Forces**: Since the glass plates are in water, the adhesive forces between the water molecules and the glass plates will be significant. These forces will cause the water to "stick" to the glass plates. 5. **Resulting Force**: The adhesive forces between the water and the glass plates create a net attractive force that pulls the plates towards each other. This is because the water molecules are attracted to the glass, and this attraction results in a force that makes it difficult to separate the plates. 6. **Conclusion**: Therefore, the force between the two glass plates when they are close together in water is an attractive force. ### Final Answer: The correct option is A: attraction. ---
