QNEET-2022-Ph-422: NEET 2022 Physics - Class 12 NEET-2022-Ph-422 Solution: Given below are two statements: Statement I: Biot-Savart's law…
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 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 from the options given below
Multiple Choice Options
- A Both Statement I and Statement II are correct
- B Both Statement I and Statement II are incorrect
- C Statement I is correct and Statement II is incorrect
- D Statement I is incorrect and Statement II is correct
Step-by-Step Verified Solution
According to Biot-Savart's law d B _ = _ 0 4 � I d l _ _ r _ r 3 which is applicable for infinitesimal element. It is analogous to Coulomb's law, where I d l _ is vector source and electric field is produced by scalar source q. Here statement I is correct and statement II is incorrect.
