A parallel plate capacitor is charged up to a potential of 300 volts. Area of the plates is `100 cm^(2)` and spacing between them is 2 cm. If the plates are moved apart to a distance of 2.5 cm without disconnected the power source, then `(in_(0)=9xx10^(-12)C^(2)N^(-1)m^(-2))`:
(i) Electric field inside the capacitor when distance when distance is 2.5 cm :
A. `6xx10^(3) V//m`
B. `3xx10^(3) V//m`
C. `12xx10^(3) V//m`
D. `15xx10^(3)V//m`
