A&C are correct.Emf induced between P&R is 3mV.
But, in the whole loop is zero

UP 3 DOWN 2
Anurag Ghosh Current in the whole loop is zero because flux is not changing?

C

because flux is not changing.?

UP 0 DOWN 2
Anurag Ghosh Consider it as a rod moving in the magnetic field.....

Chandra Prakash Mishra if you take it as two rods then the the induced emf will cancel each other

Aditya have a look at question 7 similar to previous one....

Anurag Ghosh Answer given is Bvl

Aditya Agarwal ok.. but while saying C, what i thought is, that since no equivalent rod cannot be drawn unlike here where a rod is given current and EMF through the entire ring will be zero.

no current flows in the circuit as there is no change in the flux
