A conical pipe shown in the figure has a water drop. The drop will tend to move towards:
Correct answer: A. Tapered end
- A. Tapered end
- B. Wider end
- C. In any direction
- D. No tendency to move
Explanation
The correct answer is a)Tapered end. The water drop will tend to move towards the tapered end of the conical pipe. This happens because the pressure in a fluid decreases as the cross-sectional area increases (according to Bernoulli's principle). Therefore, the water drop will move from the wider end (lower pressure) towards the tapered end (higher pressure).

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
