Question

2.The force of attraction between two objects is ------------------------------- proportional to the product of their masses and--------------------------------- proportional to the square of a distance between them.
​

Answer 1

Answer:

It is the Newton's Law of Gravitation:

The force of attraction between two objects is directly proportional to the product of their mazses and inversely proportional to the square of a distance between them.

Answer 2

Answer:

⇒ The force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of a distance between them.

✴ The law of Gravitation :

• The law of gravitation is strictly true for point masses.

However, it is valid in the following circumstances also :

• For two bodies at any size provided they both have spherical symmetry.
• When one body has spherical symmetry and the other is small compared with the separation b/w their centres.
• When neigher body has spherical symmetry but both are small compared with the separation b/w their centres.

➳ The law of gravitation is universally valid. It applies to small objects on the earth, planets in the solar system and to galaxies.
