Answer:
28,400 N
Explanation:
Let's start by calculating the pressure that acts on the upper surface of the hatch. It is given by the sum of the atmospheric pressure and the pressure due to the columb of water, which is given by Stevin's law:
On the lower part of the hatch, there is a pressure equal to
So, the net pressure acting on the hatch is
which acts from above.
The area of the hatch is given by:
So, the force needed to open the hatch from the inside is equal to the pressure multiplied by the area of the hatch:
This question involves the concept of Colomb's Law and electrostatic force.
The electrostatic force will be "6.2 x 10⁻⁸ N".
<h2>COLOMB'S LAW:</h2>According to Colomb's Law, every charge exerts an electrostatic force on the other charge, which is directly proportional to the product of the magnitudes of both the charges and inversely proportional to the square of the distance between them.
where,
- F = electrostatic force = ?
- k = Colomb's constant = 9 x 10⁹ N.m²/C²
- q₁ = magnitude of first charge = 1.6 x 10⁻¹⁹ C
- q₂ = magnitude of second charge = 1.6 x 10⁻¹⁹ C
- r = distance between charges = 61 x 10⁻¹² m
Therefore,
F = 6.2 x 10⁻⁸ N
