Electrostatic force changes like the inverse square of the distance (just like gravity).
If you double the distance, you change the force to 1/4 of what it used to be.
After the move, Objects 1 and 2 attract each other with a force of (18/16) = 1.125 units .

Explanation:
force is how hard it is pulled or pushed
The distance travelled by the ball that is thrown horizontally from a window that is 15.4 meters high at a speed of 3.01 m/s is 5.34 m
s = ut + 1 / 2 at²
s = Distance
u = Initial velocity
t = Time
a = Acceleration
Vertically,
s = 15.4 m
u = 0
a = 9.8 m / s²
15.4 = 0 + ( 1 / 2 * 9.8 * t² )
t² = 3.14
t = 1.77 s
Horizontally,
u = 3.01 m / s
a = 0 ( Since there is no external force )
s = ( 3.01 * 1.77 ) + 0
s = 5.34 m
Therefore, the distance travelled by the ball before hitting the ground is 5.34 m

As temperature decreases, the steel will contract (volume decreases) thereby, an increase in Density.
