As shown in the figure, a very thin sheet of aluminum is placed in between the plates of the condenser. Then the capacity

A

Will increase

B

Will decrease

C

Remains unchanged

D

May increase or decrease

Text Solution

Verified by Experts

The correct Answer is:
C

Since aluminium is a metal, therefore field inside this will be zero. Hence it would not affect the field in between the two plates, so capacity `=(q)/(V)=(q)/(Ed)` remains unchanged.
Aliter :
As capacity of conductor `C=(Aepsilon_(0))/(d-t)`
as `trarr0, C=(Aepsilon_(0))/(d)`
i.e. does not change.
