A horizontal telephone wire `10^(3)` m long is lying along east west in earth's magnetic field. It falls freely to the ground from a height of 10m. The emf induced in the wire when the wire strikes emf induced in the wire when the wire strikes the ground will be `(B_(H)=0.32xx10^(-4)T,g=9.8m//s^(2))`
