Which of the following statement state the importance of the universal law of gravitation? I. The motion of planets around the Sun II. The tides due to the moon and the Sun
Both I and II
The universal law of gravitation, given by Isaac Newton, states that every body in the universe attracts every other body with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
Statement I is correct: the gravitational pull of the Sun keeps the planets in their orbits, so the motion of planets around the Sun is explained by this law.
Statement II is also correct: the gravitational attraction of the Moon and the Sun on the ocean water causes the rise and fall of tides.
The same law also explains phenomena such as the motion of the Moon around the Earth and the binding of objects to the Earth's surface.
Since both the given statements describe real applications and importance of the universal law of gravitation, both are valid.
Hence the option covering both statements is the required answer.
Therefore, the correct answer is Both I and II.
