358777 An electric field of \(300\,\;V/m\) is confined to a circular area \(10\;cm\) in diameter. If the field is increasing at the rate of \(20\,\;V/m - s\), the magnitude of magnetic field at a point \(15\;cm\) from the center of the circle will be-

1 \(1.85 \times {10^{ - 17}}\;\,T\)
2 \(1.85 \times {10^{ - 15}}\;\,T\)
3 \(1.85 \times {10^{ - 16}}\;\,T\)
4 \(1.85 \times {10^{ - 18}}\,\;T\)
