Answer to Question #260316 in Physics for Lisa

Question

Calculate the surface tension force along the rim of the beaker with water having a radius of 5 cm and the angle of 10o. The coefficient of surface tension of water is 0.073 N/m. Note that L = 2πr 6. Suppose a horizontal circular loop of wire has a diameter of 5 cm and is lowered into sample of crude oil and suppose the additional force that is required to pull the loop out of the oil is 0.04N.Calculate the surface tension of the sample of crude oil.
