On the Electrostatic Interaction between Point Charges due to Dielectrical Shielding
Long T. Nguyen, Kim Tuan Do, Duy V. Nguyen +1
How will the electrostatic interaction between two point charges change if they are shielded from the other by a dielectrical slab? While the physical setting of this electromagnet…
