A liquid jet of 5 cm diameter has a pressure difference of N/m2. (Take surface tension as 0.075 N/m)

A liquid jet of 5 cm diameter has a pressure difference of N/m2. (Take surface tension as 0.075 N/m) Correct Answer 1.5

p = σ/d where p = pressure difference between the bubble and the surrounding medium, σ = surface tension and d = diameter of the bubble. Substituting all the values, p = 0.075 / 5 * 10-2 = 1.5 N/m2.
