An infinite sheet in xy plane has a uniform surface charge density `sigma`. The thickness of the sheet is infinitesimally small. The sheet begins to move with a velocity `vec(v)=v hat(i)` (i) Find the electric field `( vec(E))` and magnetic field `(vec(B))` above and below the sheet. (ii) If the velocity of the sheet is changed to `vec(v)=vhat(k)` , find the electric and magnetic field above and below the sheet.

Answer» Correct Answer - (1) `E=sigma/(2in_(0))` perpendiculary away from the sheet
`B=(mu_(0)sigmav)/2` parallel to the sheet in `-ve` and `+ve` y direction
(2) E= same as in (1);`B=0`
