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
The weight of an object was 60 N when measured on the surface of the earth. What would be its weight when measured on the surface of the moon?
Seven people, A, B, C, L, X, Y, and Z are sitting in a row, facing north. No one sits to the right of Y. Only three people sit between Y and C. Only two people sit between C and Z. B sits third to the left of X. L sits to the immediate right of X.
How many people sit between A and Z?
The universal constant of gravitation G has the unit
- An object's apparent weight is slightly less at the Earth's equator compared to its poles. This difference is primarily attributed to:
The gravitational force of attraction between two bodies is ‘F’ N. If each mass and distance between them is doubled, then the force of attraction between them is:
