Solution
The correct option is D full length of tube
The surface tension force tends to create excess pressure inside the meniscus causing the water in capillary tube to rise. This rise is controlled by the gravitational force acting on water downwards.In an artificial satellite revolving earth, the gravitational force is cancelled by the centripetal force and hence the environment is gravityless.Therefore no force is present to control the rise in tube, and it rises to full length.
