Answer :
Final answer:
The capillary rise in a tube is inversely proportional to its diameter. Hence, the narrower tube (B) will have a higher capillary rise than the wider tube (A), but the question's options do not accurately describe this relationship.
Explanation:
The question is related to capillary action, which is a physics concept describing the ability of a liquid to flow in narrow spaces without the assistance of external forces (like gravity). According to the principles of capillary action, the height to which a liquid can rise in a capillary tube is inversely proportional to the diameter of the tube.
This means that the narrower the tube, the higher the capillary rise. Consequently, if tube (B) has half the diameter of tube (A), the capillary rise in tube (B) will be higher than in tube (A). Therefore, among the given options, 'Capillary rise in tube (B) is twice of tube (A)' is incorrect, and the correct statement is that the capillary rise will be higher in the tube with the smaller diameter, which is tube (B).
Option (D) stating 'Capillary rise in both tubes is the same' is also incorrect because the rise depends on the tube's diameter. The correct choice should simply state that capillary rise in tube (B) is higher than in tube (A) because of its smaller diameter.
