In the Hall effect, we have a current flowing in the presence of a uniform magnetic field, and we get a potential difference across the conductor. Which is incorrect statement?A. a changing magnetic field produces an induced EMFB. charges are bent from their paths until an electric field is built up transverse to the wire to stop them from bendingC. the charges in the wire are moving. So the electric fields are changing with time.D. the charges produced by the current repel each other, and produce a build up of charge on the surface of the conductor.

1.	In the Hall effect, we have a current flowing in the presence of a uniform magnetic field, and we get a potential difference across the conductor. Which is incorrect statement?A. a changing magnetic field produces an induced EMFB. charges are bent from their paths until an electric field is built up transverse to the wire to stop them from bendingC. the charges in the wire are moving. So the electric fields are changing with time.D. the charges produced by the current repel each other, and produce a build up of charge on the surface of the conductor.
Answer» Correct Answer - A::C::D (B) `qE=qvB` take effect is due to force on moving charge

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
