A condenser of capacity `50pF` is connected to an `AC` supply of `220 V 50Hz`. The `rms` value of magnetic field at a distance of `5cm` from the axis is

A

`22 pi xx 10^(-14)` T

B

`22 pixx10^(-12)` T

C

`44 pi xx10^(13)` T

D

`(11)/(5)pixx10^(-12)` T

Text Solution

Verified by Experts

The correct Answer is:
B
`i_("rms") = (E_("rms"))/(X_(C)) , B_("rms")= (mu_(0)i_("rms"))/(2pir)`
