ElectroMagnetic InductionHard
Question
An athelete runs at a velocity of 30 km/hr. towards east with a 3 meter rod. The horizontal component of the earth is 4 × 10-5 weber/m2. If he runs, keeping the rod (i) horizontal and (ii) vertical, the potential difference between the ends of the rod in both the cases, will be:
Options
A.Zero in vertical case and 1 × 10-3 V in the horizontal case.
B.1 × 10-3 V in vertical case and zero in the horizontal case.
C.Zero in both the cases.
D.1 × 10-3 V in both the cases.
