MCQ

Which one statement is correct ? A parallel plate air condenser is connected with a battery. Its charge, potential, electric field and energy are $Q_0, V_0, E_0$ and $U_0$ respectively. In order to fill the complete space between the plates a dielectric slab is inserted, the battery is still connected. Now the corresponding values Q, V, E and U are in relation with the initially stated as

A
$Q>Q_0$
B
$U>U_0$
C
$V>V_0$
✓
$a,b$

✓

Answer

Correct option: D.

$a,b$

(d) $a,b$
