Hairs of shaving brush cling together when it is removed from water due to
- A force of attraction between hairs
- B surface tension
- C viscosity of water
- D characteristic property of hairs
Answer & Solution
Correct Answer
(B) surface tension
Step-by-step Solution
Detailed explanation
Surface tension is a property of fluid due to which surface of the liquid tends to acquire minimum surface area. Due to this phenomenon when the shaving brush is taken out of water, the hair cling together to minimise surface area.
