AI Thread Summary
Placing a dielectric rod between two electric charges does not change the total force exerted on the charges. The electric field inside the dielectric is reduced compared to the external field, but the forces acting on the charges outside the dielectric remain unchanged. The discussion relies on conceptual understanding rather than algebraic equations. The initial assumption is that the force remains the same, aligning with principles related to capacitors. Verification from an expert is sought to confirm this reasoning.

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

 
Physics news on Phys.org
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

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
