362631 In a hydrogen atom, an electron is revolving in the orbit of radius \(0.53{\rm{ }}A^\circ \) with \(6.6 \times 10^{15}\) revolutions per second. Magnetic field produced at the centre of the orbit is

1 \(0.125\;Wb\;{m^{ - 2}}\)
2 \(1.25\;Wb\;{m^{ - 2}}\)
3 \(12.5\;Wb\;{m^{ - 2}}\)
4 \(125\;Wb\;{m^{ - 2}}\)

362633 Given below are two statements:
Statement I: Biot-Savart's law gives us the expression for the magnetic field strength of an infinitesimal current element (Idl) of a current carrying conductor only.
Statement II: Biot-Savart's law is analogous to Coulomb's inverse square law of change \(q\), with the former being related to the field produced by a scalar source, Idl while the latter being produced by a vector source, \(q\).
In light of above statement choose the most appropriate answer from the options given below.

1 Both statement I and Statement II are incorrect
2 Statement I is correct and Statement II is incorrect
3 Statement I is incorrect and Statement II is correct
4 Both Statement I and Statement II are correct.
