AP EAMCET2012PhysicsElectromagnetic Induction
A straight conductor of length 4 ~m moves at a speed of 10 ~m / s . When the conductor makes on angle of 30^ with the direction of magnetic field of induction of 0.1 ~Wb - m ^2 , then induced emf is
Options
- A8 ~V
- B4 ~V
- C1 ~V
- D2 ~V
Correct answer
D. 2 ~V
Step-by-step solution
Induced emf is given by aligned e & =B v l & =0.1 10 < 4 30=2 ~V aligned
