MCQ
The action of a nib split at the top is explained by
- AGravity flow
- BDiffusion of fluid
- ✓Capillary action
- DOsmosis of liquid
✓
Answer
Correct option: C.
Capillary action
c
(c) The tip of nib of a writing pen is split to provide the capillary action.
(c) The tip of nib of a writing pen is split to provide the capillary action.
Due to capillarity, ink will rise in the split of nib and allows the pen to write continuously.
