Question

Two identical metal plates, separated by a distance d form a parallel plate capacitor. A metal sheet of thickness$2dβ$ of the same area as that of either plate, is inserted between the plates. The ratio of the capacitance's after the insertion of the sheet to that before insertion is:

Verified by Toppr

Correct option is

The effective capacitance of above capacitance is series combination ofΒ $d4Ο΅_{0}Aβ$ and $d4Ο΅_{0}Aβ$

$βC_{q}1β=4Ο΅_{0}Adβ+4Ο΅_{0}Adβ$

$βC_{eff}=d2Ο΅_{0}Aβ$

$C_{1}C_{2}β=dΟ΅_{0}Aβd2Ο΅_{0}Aββ=2:1$
