NEET Physics Surface Tension MCQ Question
What is the pressure difference across the surface of a liquid in a capillary tube given by the formula (P_i - P_o)?
(2S/r)
(S/2r)
(S/r^2)
(4S/r)
Correct Answer
Detailed Explanation
The pressure difference across the surface of a liquid in a capillary tube is given by the equation (P_i - P_o) = (2S/r), which highlights the relationship between surface tension and pressure difference at the liquid's surface.
