Gravity is an attractive force that decreases as the mass of an object increases.
a. true
b. false

The correct answer to the question is - False i.e gravitational force does not decrease as mass of the object increases.

EXPLANATION:

From Newton's law of gravitation, we know that every body in the universe attracts every other body with a force called gravitational force.

Let us consider two bodies having masses M and M' respectively.

Let the two bodies are separated by a distance of R from their centre of masses.

The gravitational force between them is directly proportional to the product of masses and inversely proportional to the square of separation distance between them.

Mathematically it can be written as -

          Gravitational force F =

Here, G is known as universal gravitational force constant.

From above, we see that force increases with the increase in mass of any object.

Hence, the statement is wrong that gravity decreases with the increase in mass of the object.
