A conducting bar moves on two conducting rails as shown in the figure. A constant magnetic field B exists into the page. The bar starts to move from the vertex at time 
with a constant velocity. If the induced EMF is 
, then value of 
is .
Text Solution
Verified by ExpertsThe correct answer is:
1
(1)
As the bar moves without change in orientation, the length of bar will be proportional to its distance from the vertex.
i.e. 
induced emf
