A liquid is coming out from a vertical tube. The relation between the weight of the drop W , surface tension of the liquid T and radius of the tube r is given by, if the angle of contact is zero

A liquid is contained in a vertical tube a semicircular cross section the contact angle is zero. The force of surface tension on the curved part & on the flat part are in ratio

A liquid is containe in a vertical tube of semicircular cross section figure.The contact angle is zero. The force of surface tension on the curved part and on the flat part are in ratio

A liquid is contain in a vertical tube of semicircular cross section figure. The contact angle is zero. The force of surface tension on the curved part and on the flat part are in ratio

A capilary tube is kept vertical and made to touch the surface of the liquid of surface tension T . If the radius of the capillary tube is 'r' . Then the force on the wall of the capillary tube is

Liquid drops are falling slowly one after the other from a vertical capillary tube of bore radius 'r' If W is weight of a liquid drop , surface tension of that liquid is

The most approprite graph between height (h) of the liquid column in a capillary tube and the radius ( r ) of the tube for a given liquid will be
