[FermatPell]

Homework Statement

Does placing a dielectric rod between two electric charges increase or decrease the total force exerted on any of the charges?

Homework Equations

Not really algebraic, only conceptual.

The Attempt at a Solution

I guess it remains same...

by placing dielectric ... only the field inside the dielectric becomes less than outside but is same as before outside dielectric ... so no force change is experienced

just a guess

used the concepts of capacitors

Some expert please verify or correct me
