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.)

Two large parallel plane sheets have uniform charge densities + sigma and -sigma. Determine the electric field (i) between the sheets, and (ii) outside the sheets.
Two uniform sheets of charge with surface charge densities +sigma and -sigma are intersecting at right angles to each other. Electric field intensity due to this system is
Two plane sheets of charge densities +sigma and -sigma are kept in air as shown in Fig. What are electric field intensities at points A and B ?
A metallic square loop ABCD is moving in its own plane with velocity v in a uniform magnetic field perpendicular to its plane as shown in the figure. An electric field is induced
A wire KMN moves along the bisector of the angle theta with a constant velocity v in a uniform magnetic field B perpendicular to the plane of the paper and directed inward. Which of the following is correct?
In the fig shown XX represents a vertical plane perpendicular to the plane of the fig. To the right of this plane there is a uniform horizontal magnetic field B directed into the plane of the fig. A uniform electric field E exists horizontally perpendicular to the magnetic field in entire space. A charge particle having charge q and mass m is projected vertically upward from point O. It crosses the plane XX after time T. Find the speed of projection of the particle if it was observed to move uniformly after time T. It is given that qE = mg.
A uniform magnetic field exists in the plane of paper pointing from left to right as shown in figure. In the field, an electron and a proton move as shown. The electron and the proton experience:
A metallic rod of length l is hinged at the point M and is rotating about an axis perpendicular to the plane of paper with a constant angular velocity omega . A uniform magnetic field of intensity B is acting in the region (as shown in the figure) parallel to the plane of paper. The potential difference between the points M and N
A square-shaped conducting wire loop of dimension a moving parallel to the x-axis approaches a square region of size b (a lt b) where a uniform magnetic field B exists pointing into the plane of the paper (see figure). As the loop passes through this region, the plot correctly depicting its speed (v) as a function of x is
