1Theory: If a rod has its velocity and length both perpendicular to B then emf is induced in it which is equal to BLV
You must remember that L B V three must be perpendicular for emf induction..
In your question....
EMF will induced in....three places...See the below figure....
Hence first option is correct
1
1or else you can just replace the whole set up with a rod in place of pq.
it's basically the same thing.
71What if the rods had considerable thickness, say half of their length?
How would the situation vary? Just a rough Idea?
1@vivek....i think in that case the area wud be considered...flux = NBA(cos theta)....
