A method used to determine the surface tension of a liquid is to determine the force necessary
Question:
A method used to determine the surface tension of a liquid is to determine the force necessary to raise a wire ring through the air-liquid interface. What is the value of the surface tension if a force of \(0.015 \mathrm{~N}\) is required to raise a 4 -cm-diameter ring? Consider the ring weightless, as a tensiometer (used to measure the surface tension) "zeroes" out the ring weight.
