Total pressure on 1 m x 1 m gate immersed vertically at a depth of 2 m below the free water surface will be:
Correct answer: B. 2000kg
- A. 1000 kg
- B. 2000kg
- C. 4000kg
- D. 8000 kg
Explanation
The total pressure on a vertical gate submerged in water can be calculated using the hydrostatic pressure formula:P=ρ⋅g⋅h⋅AThe total pressure is given by the product of pressure and area:Total Pressure=P⋅ATo convert Newtons to kilograms (1 kg = 9.8 N), we divide by 9.8:Total pressure= 19600N/9.8N/kgTotal Pressure≈2000kg

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.
