Answer 1

Given:

The gravitational force between objects A and B is F = 5 N

To find the force when distance is reduced to half.

Step-by-step explanation:

The gravitational force is calculated by the formula

`\begin{gathered} F=(Gm_Am_B)/(r^2) \\ =5\text{ N} \end{gathered}`

Here, G is the universal gravitational constant.

m_A is the mass of object A

m_B is the mass of object B

r is the distance between the objects.

The new distance is r'=r/2

The new gravitational force will be
