NEET Physics Surface Tension MCQ Question
Consider a flat vertical glass plate partially submerged in a liquid, as described in the NCERT context. If the liquid just touches the glass plate and pulls it down due to surface tension, which factor primarily determines the amount of additional weight needed to balance the plate?
The surface tension of the liquid.
The density of the liquid.
The viscosity of the liquid.
The temperature of the liquid.
Correct Answer
Detailed Explanation
The additional weight required to balance the plate is determined by the surface tension of the liquid, as it causes the liquid to pull the plate down.
