Suppose that the electric flux inside a parallel plate capacitor changes at a rate of `7xx10^(14)` units/sec, then the magnetic induction field density at any points inside the capacitor is,
[Area of the plate of the capacitor=`1 m^(2)`
Permittivity of free space =`8.8xx10^(-12)Nm^(2)c^(-2)`
Permeability of free space =`4pixx10^(-7)`Teslam/Amp]

Options

A. `7.79xx10^(-3)T`
B. `0.779xx10^(-5)T`
C. `8.85xx10^(-4)T`
D. `88.5xx10^(-12)T`

Explanation

Magnetic induction field density is given by,
`intB.dl=mu_(0)(epsilon_(0)(dphi)/(dt))`
`impliesB2pirl=1/c^(2)(dphi)/dt`
`impliesB=(1)/(2pirc^(2))(dphi)/(dt)=2xx10^(-3)T`
