Force between two identical charges placed at a distance of `r` in vacumm is `F`.Now a slab of dielectric constant 4 is ijnserted between these two charges . If the thickness of the slab is `r//2`, then the force between the charges will becomes

Force between two identical charges placed at a distance of r in vacume is F . Now a slab of dielectric constant 4 is inserted between these two charges . If the thickness of the slab is r//2 , then the force between the charges will becomes

Force between two identical charges placed at a distance of r in vacuum is F .Now a slab of dielectric constant 4 is inserted between these two charges . If the thickness of the slab is r//2 , then the force between the charges will becomes

Force between two charges separated by a distance r varies as r^(2) ?

If a dielectric is placed between two charges in place of vacuum or air, then the force between the charges will

Two charges are placed in vacuum at a distance d apart. The force between them is F. if a medium of dielectric constant 2 is introduced between them, the force will now be

The force between two charges in free space is F. If a dielectric medium of dielectric constant K is placed the force between two charges is…………

The force of repulsion between two identical positive charges when kept with aseparation r in air is F. half the gap between the two charges is filled by a dielectric slab of dielectric constant = 4. thenthe new force of repulsion between those two charges becomes
