Which of the following forces is responsible for the tides, due to the Moon and the Sun?
Gravitation force
The concept of tides originates from the gravitational interactions between the Earth, the Moon, and the Sun. Tides are the periodic rise and fall of sea levels caused primarily by these gravitational forces. Let's identify which force plays a crucial role in this phenomenon:
1. Electromagnetic force: This is one of the fundamental forces, responsible for interactions between charged particles. It is unrelated to tides.
2. Nuclear force: This force acts within atomic nuclei, holding protons and neutrons together. It has no direct influence on tidal phenomena.
3. Gravitation force: This is the attractive force between all masses; it’s the primary force causing the tides due to the Moon and Sun's gravitational pull on Earth's oceans.
4. Electrostatic force: Like the electromagnetic force, this involves interactions between charged particles, and also does not affect tides.
Considering these points, the correct answer is the Gravitation force, as it is the force responsible for the occurrence of tides influenced by the gravitational pull of the Moon and the Sun on Earth's water bodies.
Important Questions from Gravitation
Which one of the following statement is true for the relation, \(F= \frac{{G{m_1}{m_2}}}{{{r^2}}}\) ?
(All symbols have their usual meanings)Suppose there are two planets, 1 and 2, having the same density but their radii are R 1and R 2respectively, where R 1> R 2. The accelerations due to gravity on the surface of these planets are related as
LIGO stands for
If radius of the earth were to shrink by 1%, its mass remains the same, g would decrease by nearly
The radius of the Moon is about one-fourth that of the Earth and acceleration due to gravity on the moon is about one-sixth that on the earth. From this, we can conclude that the ratio of the mass of earth to the mass of the moon is about
