The unit of surface tension is same as that of _________(a) surface en

1.	The unit of surface tension is same as that of _________(a) surface energy per unit volume(b) force per unit area(c) surface energy per unit area(d) surface energy per unit lengthThis question was addressed to me during a job interview.This is a very interesting question from Fluids Mechanical Properties topic in section Mechanical Properties of Fluids of Physics – Class 11
Answer» Correct ANSWER is (C) surface energy per unit area Explanation: Surface tension is defined as force per unit LENGTH or surface energy per unit area.The unit is therefore N/m.Another unit people use is J/m^2 (where J REFERS to joule, the unit of energy).But obviously it is EQUAL to Nm/m^2= N/m.
