A) 2.52V
B) 25.2V
C) 5.26V
D) 1.26V
Correct Answer: A
Solution :
Let a rod of length I moves with velocity\[v,\]in a magnetic field B. Because of change in magnetic flux passing through the circuit, an emf is induced in the circuit, it is given by \[e=Bvl\] Given, \[B=0.9\text{ }Wb/{{m}^{2}},\text{ }v=7\text{ }m/s,\text{ }I=0.4\text{ }m\] \[\therefore \] \[e=0.9\times 7\times 0.4=2.52V\]You need to login to perform this action.
