An evacuated spherical diving bell containing a camera is in the ocean at a depth of 145 m. It has a flat, transparent, circular

port with a diameter of 17.1 cm. Find the magnitude of the total force exerted by the seawater on the port. For the density of seawater use 1025 kg/m3.
Calculate the total pressure at the given depth by adding up the atmospheric pressure (1.01e5 N/m2) plus the pressure due to the sea water. Evacuated means that that there is no air in the bell.

Answer:

Explanation:

pressure at the 145 m depth = atmospheric pressure + pressure due to depth of seawater = 1.01 × 10⁵ N/m² + ρgh where ρ is density of sea water = 1025 kg/m3, g = 9.8 m/s² and depth h = 145 m

pressure at the 145 m depth = 1.01 × 10⁵ N/m²  + 14.57 × 10⁵ N/m² = 15.58 ×  10⁵ N/m²

total pressure = F / A

F = total pressure × A

A area = πr² = 3.142 × 0.0855² = 0.02297 m²

F = 15.58 ×  10⁵ N/m² ×0.02297 m² = 3.58 × 10⁴ N

melomori [17]

Explanation:

It is known that opposite charges tend to attract each other whereas like charges tend to repel each other.

For example, when we rub a plastic pen with wool and it gets attracted towards an invisible tape then it means that there is an opposite charge present on both the objects.

A neutral object also tends to develop a charge when it comes in contact with a charged object.

Thus, we can conclude that the following statements are true.

  • The tape might be positively charged.
  • The tape might be uncharged.
