NEET 2022 Question Paper Mock Test

Given below are two statements:Statement I: Biot-Savart's law gives 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 charge $q$, 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 statements choose the most appropriate answer:

In the given nuclear reaction, the element $X$ is:
