हिन्दीGiven below are two statements:\n Statement I: Biot-Savart's law gives us the expression for the magnetic field strength of an infinitesimal current element (\( I\,dl \)) of a current carrying conductor only.\n 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, \( I\,dl \) while the latter being produced by a vector source, \( q \).\nIn light of above statements choose the most appropriate answer from the options given below:
Correct answer · Option 1
Statement I is correct and Statement II is incorrect.
Explanation
Statement I is correct. Statement II is incorrect because \( I\,dl \) is a vector source while charge \( q \) is a scalar source (reversing the roles described in statement II).
