Answer:
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".

The correct answer is a
Explanation:
At projectile launch speeds are
X axis vₓ = v₀ = cte
Y axis = v_{oy} –gt
The moment is defined as
p = mv
For the x axis
pₓ = mvₓ = m v₀ₓ
As the speed is constant the moment is constant
For the y axis
p_{y} = m v_{y} = m (v_{oy} –gt) = m v_{oy} - m (gt)
Speed changes over time, so the moment also changes over time
Let's examine the answer
i True
ii False. The moment changes with time
The correct answer is a
