Consider a thin metallic sheet perpendicular to the plane of the paper moving with speed `upsilon` in a uniform magnetic field B going into the plane of the paper (See figure.) If charge densities `sigma_1 and sigma_2` are induced on the left and right surfaces, respectively, of the sheet then (ignore fringe effects.)
A
`sigma_1=(in_0upsilonB)/(2),sigma_2=(- in _0upsilon B)/(2)`
