Question

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 $4 	imes {10^{ - 5}}Wb/{m^2}$. 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

Accepted Answer

$1 	imes {10^{ - 3}}V$ in vertical position and zero is horizontal position

Answer

Zero in vertical position and $1 	imes {10^{ - 3}}V$ in horizontal position

Answer

Zero in both cases

Answer

$1 	imes {10^{ - 3}}V$ in both cases
