A player with 3 m long iron rod runs towards east with a speed of 30 km/hr. Horizontal component of earth's magnetic field is\[4\times {{10}^{-5}}Wb/{{m}^{2}}\]. If he is running with rod in horizontal and vertical positions, then the potential difference induced between the two ends of the rod in two cases will be [MP PET 1993]

• A.            Zero in vertical position and \[1\times {{10}^{-3}}V\]in horizontal position
• B.            \[1\times {{10}^{-3}}V\]in vertical position and zero is horizontal position
• C.            Zero in both cases
• D.            \[1\times {{10}^{-3}}V\]in both cases
