Consider a long straight wire of cross-sectional area A carrying a current i.Let there be n free electrons per unit volume.An observer places himself on a trolley moving in the opp. direction to the current with a speed v=i/(nAe) and separated from the wire by a distancer.the magnetic field as seen by the observer is very nearly(a) µo i/2pr(b) µo i/pr(c) µo i/2pr(d) 0a steady electric curr.is flowing thru a cylindrical conmductor .(a)the electric field at the axis of the conductor is zero(b)The magnetic field at the axis of the conductor is zero.(c)The electric field at the vicinity of the conductor is zero.(d)The magnetic field at the vicinity of the conductor is zero.let E and B (vectors) denote electric and magnetic fields in a frame S and E’ and B’ (vectors) denote electric and magnetic fields in a frame S’ moving with a velocity v w.r.t S.2 of the following equations r wrong.(a)B’y=By+vEz/c2(b)E’y=Ey-vBz/c2(c)B’y=By+vEz(d) E’y=Ey+vBzplease give detailed reasons for all questionsis there NE source for solutions 2 HCV objectives
