Question

Magnetic field is produced by moving charged particles of a charged particle having charge is moving with a velocity w then magnetic field at a point is given by B = B where 7 where is position vector of point pwrt moving charge Now suppose a stationary infinite wire is carrying a current than new where an offee elections 9 volume. A area of cross section of wire V, the constant velocity with which electrons can be assumed to be moving and e is electronic charge so we can cut magnetic field at a point which is at a distance x from the wres in the ground trame This comes out to be B Suppose a charged place is fixed with respect to ground an observer song with respect to ground with some velocity Velocity of observer is very small as compared to velocity of light Then incorrect statement of the following​

Answer 1
