उत्तर
increase
Oil between the plates of the capacitor acts as a dielectric. We know that the electric field decreases by a factor of `1/K` of the original field when we insert a dielectric between the plates of a capacitor (K is the dielectric constant of the dielectric). So, if the oil is pumped out, the electric field between the plates will increase, as the dielectric has been removed.
