The hair of shaving brush clings together when removed from waterdue to A Elasticity B Friction C Viscosity D Surface tension View Answer Discuss in Forum Answer & Explanation Answer : Option D Explanation : Surface tension.Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force.g. It is revealed, for example, in the floating of some objects on the surface of water, even though they are denser than water, & in the ability of some insects (e. water striders) to run on the water surface. This property is caused by cohesion of similar molecules, & is responsible for many of the behaviors of liquids. In the present case, as the forces inside the molecules of water also pulls in the hair on the shaving brush as they have less mass, due to this tension in the surface of the water the hair sticks together.
