A square frame of side \(10\;\,cm\) and a long straight wire carrying current \(1\;\,A\) are in the plane of the paper. Starting from close to the wire, the frame moves towards the right with a constant speed of \(10\;\,m{s^{ - 1}}\) (see figure). The e.m.f induced at the time the left arm of the frame is at \(x = 10\,cm\) from the wire is :
358482 A satellite orbiting very close to surface of the earth has a \(2\,\;m\) long antenna oriented perpendicular to the earth's surface. At the equator the earth's manetic field is \(8 \times {10^{ - 5}}\;T\) and is horizontal. Assuming the orbit to be circular, find emf induced across the ends of the antenna.
