Expert Answer
(1) Electric field energystored in the capacitor = (1/2)CV2
Where C is equivalent capacitance C and V is potential difference across capacitor plates.
By introducing dielectric material of dielectric constant K, Capacitance increases by a factor of K .
But Capacitors are connected same battery, potential difference remains same.
Hence Electric field is increaed by a factor of K
-----------------------------------------------------------------------
(2) Charge Q on capacitor C is given as, Q = C V
when capacitance increases by K by introducing dielectric material of dielectric constant K, but potential difference remains same,
Charge on capacitor increases by a factor K
-------------------------------------------------------------
(3) potential difference does not change , since same battery of constant EMF is connected acros capacitors.
