Physics-Surface Tension
NEET Physics Surface Tension MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Imagine a diagram showing a flat vertical glass plate balanced on one arm of a balance, with a vessel of liquid being raised until it touches the plate. What does this setup demonstrate in the context of surface tension?
A
The measurement of surface tension by the force exerted on the plate.
B
The determination of the viscosity of the liquid.
C
The effect of gravity on the shape of liquid drops.
D
The calculation of fluid density using buoyant force.
Correct Answer
Option A
Detailed Explanation
The setup described is used to measure surface tension by observing the force required to lift the glass plate as the liquid adheres to it, reflecting the attraction between the solid and liquid.
