JEE Main2004PhysicsElectromagnetic InductionActual
A metal conductor of length 1 ~m rotates vertically about one of its ends at angular velocity 5 radians per second. If the horizontal component of earth's magnetic field is 0.3 10⁻⁴ ~T , then the e.m.f. developed between the two ends of the conductor is
Options
- Adepends on the nature of the metal used
- Bdepends on the intensity of the radiation
- Cdepends both on the intensity of the radiation and the metal used
- Dis the same for all metals and independent of the intensity of the radiation.
Correct answer
B. depends on the intensity of the radiation
Step-by-step solution
emf. developed is given by _ ind = 1 2 ~B R ^2=50 V .
