![In measuring the surface tension of a
liquid (drop weight method), 20 drops of
the liquid (r = 0.2cm) falling apart from

found to weight 0.95 gram. What is the
surface tension of the liquid?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F60fff8aa-0eb9-4de9-8233-4f474d77189b%2F7bff45af-8e7c-4c9c-b59f-5bccd179ea1d%2Fvoqwlmr_processed.jpeg&w=3840&q=75)

W : mass
r : radius
y : surface tension
Therefore,
y = 0.94/(2*3.14*0.2)
y = 0.7484 g/cm
