Question

Objects 1 and 2 attract each other with a electrostatic force

of 18.0 units. If the distance separating Objects 1 and 2 is
changed to four times the original value (i.e., quadrupled),
then the new electrostatic force will be units.

Answer 1

1.125

Step-by-step explanation:

Answer 2

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 .
