A square metal sheet 2.8 cm on a side and of negligible thickness is attached to a balance and inserted into a container of fluid. The contact angle is found to be zero, as shown in Figure a, and the balance to which the metal sheet is attached reads 0.40 N. A thin veneer of oil is then spread over the sheet, and the contact angle becomes 180, as shown in Figure b. The balance now reads 0.39 N. What is the surface tension of the fluid? N/m Need Help?
