The capacitance of a parallel plate capa...

The capacitance of a parallel plate capacitor with air as Medium is `6 muF`. With the introduction of a dielectric medium,the capacitance becomes `30muF`. The permittivity of the medium is:

A

`1.77 xx 10^(-12) C^(2)N^(-1)m^(-2)`

B

`0.44 xx 10^(-10) C^(2)N^(-1)m^(-2)`

C

`5.00 C^(2)N^(-1)m^(-2)`

D

`0.44 xx 10^(-13) C^(2)N^(-1)m^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(m)= epsi_(r ) C_(e )`
`epsi_(r )= (30)/(6)=5`
`epsi= epsi_(0), epsi_(r )=8.85 xx 10^(-12) xx5`
`epsi= 0.44 xx 10^(-10)`
