Two points charges `Q_(1)` and `Q_(2)` placed at separation `d` in vacuum and force acting between them is `F`. Now a dielectric slab of thickness `d//2` and dielectric constant `K = 4` is placed between them. The new force between the charges will be

Two point charges are placed at separation d in vacuum and the force between them is F . Now a dielectric slab of thickness t = d//3 and dielectric constant K is placed between the charges and the force becomes 9F//25 . Find the value of K .

Two similar point charges q_1 and q_2 are placed at a distance r apart in the air. The force between them is F_1 . A dielectric slab of thickness t(ltr) and dielectric constant K is placed between the charges . Then the force between the same charge . Then the fore between the same charges is F_2 . The ratio is

A dielectric slab of thickness t(ltr) and dielectric constant K is placed between the charges . Then the force between the same charge . Then the fore between the same charges is F_2 . The ratio is

Two charges are at distance (d) apart in air Coulomb force between them is F. If a dielectric material of dielectric constant (K) is placed between them, the coulomb force now becomes.

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