Work done required to displace a movable wire by 2 cm in the given frame is 6 x 10^ -4 J. Find out the surface tension. |
| Answer» As we all know that surface tension acts on the liquids exactly perpendicular to them, it is defined as force per unit length. There is one more way in which you can define it that is it is equal to surface energy by area. Both these formulas are very important as u can easily solve surface tension questions by using these formulasAs we all know that surface tension acts on the liquids exactly perpendicular to them, it is defined as force per unit length.
