A satellite with a 40 cm long copper wire on its bottom is revolving around the earth at 7.8 km per second, such that the wire is perpendicular to the vertical component of earths' magnetic field. Determine the e.m.f. induced across this wire, if the magnitude of the vertical component of magnetic field is 0.2 gauss.
