Two water pipes of diameters 4 cm and 8 cm are connected to a supply line. The velocity of flow of water in the pipe 4 cm diameter is:
Correct answer: B. 4 times
- A. ¼ times
- B. 4 times
- C. Twice
- D. ½ of 8 cm diameter pipe
Explanation
The velocity of flow of water in a pipe is inversely proportional to the square of its diameter, according to the principle of continuity.Mathematically, the equation is:v1 /v2 =(d22 /d12 )

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
