A) \[8.15\times {{10}^{-11}}\]
B) \[0.44\times {{10}^{-10}}\]
C) \[15.2\times {{10}^{12}}\]
D) \[1.6\times {{10}^{-14}}\]
Correct Answer: B
Solution :
The capacitance of air capacitor is given by \[=1-\frac{3}{5}\] ...(1) When a dielectric of permittivity \[C=\frac{10}{2\times {{10}^{4}}}=5\times {{10}^{-4}}\] and dielectric constant K is introduced between the plates, then \[\therefore \] ....(ii) Dividing Eq. (ii) by Eq. (i) we get \[C=500\mu F\] \[{{C}_{0}}=\frac{{{\varepsilon }_{0}}A}{d}=3\mu F\] K = 5 So, the permittivity of the medium \[{{\varepsilon }_{r}}\] \[C=\frac{K{{\varepsilon }_{0}}A}{d}=15\mu F\] \[{{V}_{A}}:{{V}_{N}}={{10}^{15}}:1\]You need to login to perform this action.
