Question

A rectangular sheet of metal ABCD with side lengths AB = a, BC = a/2 and thickness t is kept with ABCD on the x-y plane. There is a uniform magnetic field B = Bk along the z direction. AB is along the x-axis. When the sheet is moved with speed v along the positive y direction, the resulting potential difference is ΔV₁. If the same sheet is moved with speed along the positive x direction, the resulting potential difference is ΔV₂. What is the value of the ratioΔV₁/ ΔV₂ ?
