Explanation:

The ball pen works on the principle of capillary action and surface tension. Explanation: Capillary action means that an ink is pulled due to the thin length of the capillary as a part of fluid moves out. When we move the pen on a piece of paper, the ballpoint of the pen slightly rotates.
