A conducting wire is bend into a loop as shown in the figure. The segment AOB is parabolic given by the equation `y^(2)=2x`, while segment BA is a straight line x = 2. the magnrtic field in the region `vec(B)=-8hat(k)` tesla and the current in wire is 2A.

If the loop were rotated about the z-axis with an angular speed of 1 rad/sec. Then magnitude of emf induced across the straight segment AC will be

Options

A. 32V
B. 8V
C. 16V
D. 4V

Explanation

The emf is the difference between emf across straight segment OA and OC.
