NEET Physics Surface Tension MCQ Question
Consider a vertical glass plate partially submerged in water, forming an angle of contact due to surface tension, as described in the NCERT. What is the relationship between the contact angle θ and the forces of attraction between the liquid and the solid surface?

A smaller contact angle indicates stronger attraction between liquid and solid.
A larger contact angle indicates stronger attraction between liquid and solid.
The contact angle is independent of the attraction between liquid and solid.
A smaller contact angle indicates weaker attraction between liquid and solid.
Correct Answer
Detailed Explanation
A smaller contact angle means the liquid is more strongly attracted to the solid, which decreases the solid-liquid surface energy.
