Question

Which statement is true about the force of gravity? It is a force of attraction. It depends on temperature. It is affected by pressure. It rarely exists between objects.

Answer 1

Answer: The correct answer is that it is a force of attraction.

Step-by-step explanation:

Force of gravity is defined as the force that attracts any two objects having mass. It is directly proportional to the product of the two masses and is inversely proportional to the square of the distance between the two masses.

Mathematically,

`F\propto m_1m_2\\\\F\propto (1)/(r^2)`

Combining the two equation and removing the proportionality sign, we get:

`F=(Gm_1m_2)/(r^2)`

where, G is the universal gravitational constant

`m_1\text{ and }m_2` are the masses of the two objects

r is the distance between the two objects.

This force is not affected by temperature and pressure.

Hence, the correct answer is that it is a force of attraction.

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

Force of gravity is defined as the force which can attract any object along with its mass.

For example, an apple falling from a tree on the ground represents that force of gravity has pulled the apple towards the ground along with its mass.

Thus, we can conclude that out of the given options, it is a force of attraction is true about the force of gravity.
