A) 4
B) 2
C) 1.5
Homework Answers
We lnow that charge on a capacitor C connected across voltage V, is Q=CV, and capacitance value with dielectric constant k is C'=kC. So for the same charge on C1 and C2 , we get,C1.V1=C2.V2. Therefore. We have the dielectric constant for C2 is 2. So that same charge on both capacitor. Hence correct oprtion is B)2 . THANK YOU. PLEASE LIKE THE ANSWER ASAP

Two air-filled parallel-plate capacitors with capacitances C1 and C2 are connected in series to a battery that has voltage V; C1 = 3.00 μF and C2 = 6.00 μF. The electric field between the plates of capacitor C2 is E02. While the two capacitors remain connected to the battery, a dielectric with dielectric constant K = 4 is inserted between the plates of capacitor C1, completely filling the space between them. After the dielectric is inserted in C1, the electric...
