The surface tension of ethanol at 25C is 18.97 x 10^-3 N/m, and its density at this temperature is 0.789 g/cm. If the radius of the capillary that allows the liquid to rise by 3.6 cm is 0.05 cm, what is the pressure difference in N/m that causes the liquid to rise? (Acceleration due to gravity is 9.8 m/s).
