Objects 1 and 2 attract each other with an electrostatic force of 18.0 units. If the distance separating objects 1 and 2 is tripled, then the new electrostatic force will be 162 units.
The non-contact forces which pull or push on objects without touching them is referred to as electrostatic force.
Assuming that the charge on each object is q and distance between then is r
Electrostatic force will be:
[tex]F=\frac{1}{4\pi\epsilon_{0} }\frac{(q^2)}{(r^2)}[/tex]
From the relation one can note that electrostatic force is inversely proportional to square of distance as given below:
[tex]\frac{F_{new}}{F}=\frac{r^2}{r^2_{new}}[/tex]
[tex]F_{new}=9F[/tex]
[tex]F_{new}=9*18[/tex]
[tex]F_{new}=162[/tex]
Thus, the answer is 162 units.
