The distance between the plates of a parallel plate condenser is 
and P.D. 
. If a 
thick slab of dielectric constant 6 is introduced between its plates, then
A
The charge on the condenser will be doubled
B
The charge on the condenser will be reduced to half
C
The P.D. across the condenser will be 
D
The P.D. across the condenser will be 
Text Solution
Verified by ExpertsThe correct answer is:
D
If nothing is said, it is considered that battery is disconnected. Hence charge remain the same
Also 
and 
⇒ ⇒ 
⇒ ⇒ 
⇒ ⇒ V m = 45V
