A copper rod of length 0.19 m is moving parallel to a long wire with a uniform velocity of 10 m/s. The long wire carries 5 ampere current and is perpendicular to the rod. The ends of the rod are at distances 0.01 m and 0.2 m from the wire. The emf induced in the rod will be-

• A. \[10\,\mu V\]
• B. \[20\,\mu V\]
• C. \[30\,\mu V\]     
• D. \[40\,\mu V\]
