Answer: Decreasing the distance of the space shuttle from Earth .
Explanation:
According to expression of gravitational force:
[tex]F=\frac{G\times m_1\times m_2}{r^2}[/tex]
G = gravitational constant
[tex]m_1, m_2[/tex] = masses of two objects
r = Distance between the two objects.
F = Gravitational force
From the above expression we can say that gravitational force is inversely proportional to squared of the distance between the two masses.
[tex]F\propto \frac{1}{r^2}[/tex]
So, in order to increase the gravitational force on space shuttle distance between the space space shuttle must be decreased.
Hence, the correct answer 'decreasing the distance of the space shuttle from Earth '.
