In which situation is the gravitational force between two objects hard to detect? (options)
a. if the mass of each object is very small.
b. if the objects are very close together.
c. if the mass of one of the objects is very great.
d. if the mass of both objects is very great.

Hence, the correct option is (A) "If the mass of each object is very small".

Explanation:

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

The mathematical expression is given by :

d is the distance between masses

Gravitational force is one of the fundamental force in the universe. If the masses of objects is too small, then their interaction with each other is hard to detect.

Hence, the correct option is (A) "If the mass of each object is very small".
