Question

gravity between two object is x. keeping the masses unchanged if the distance between the object is halfed than the magnitude of gravity will change by which factor?

Answer 1

G= m1xm2    here g= gravitational constant                                                        
        r^2               m1 and m2 are the masses.
                                          and r is the distance between them.
 so g α 1/r^2. so when  r is halved the g becomes 4 times = 4x      

Answer 2

$F\ =\ Gravity\ =\ x\ =\ \frac{GMm}{d^2} \\ \\ \ d\ is\ halved,\ then,\ F_1 = G M m \frac{1}{d/2)^2} = G M m \frac{4}{d^2} = 4 x$

The Force or gravity becomes 4 times.
