A cylindrical region of radius 1 m has instantaneous homogenous magnetic field of 5T and it is increasing at a rate of 2T/s. A regular hexagonal loop ABCDEFA of side 1 m is being drawn in to the region with a constant speed of 1 m/s as shown in the figure. What is the magnitude of emf developed in the loop just after the shown instant when the corner A of the hexagon is coinciding with the centre of the circle?

1.	A cylindrical region of radius 1 m has instantaneous homogenous magnetic field of 5T and it is increasing at a rate of 2T/s. A regular hexagonal loop ABCDEFA of side 1 m is being drawn in to the region with a constant speed of 1 m/s as shown in the figure. What is the magnitude of emf developed in the loop just after the shown instant when the corner A of the hexagon is coinciding with the centre of the circle?
A.	\[5/\sqrt{3}V\]
B.	\[2\pi /\sqrt{3}V\]
C.	\[(5\sqrt{3}+2\pi /3)\,V\]
D.	\[(5\sqrt{3}+\pi )\,V\]
Answer» D. \[(5\sqrt{3}+\pi )\,V\]
