The electric field intensity between the plates of a capacitor decreases from ` 40 = frac (vo l t)m` to `35 =frac (vo l t)m` by iserting a glass plate. Calculate the dielectric constant of glass.

The electric field intensity between the plates of a parallel plate capacitor decreases by 20%, when a dielectric slab is inserted between the plates. Find the dielectric constant of the dielectric.

Correct the realtion Farad = frac (Vo l t) (Co u lomb)
