A uniform magneitc field B fills a cylindrical volume of radius R, A metal rod of length l is placed as shown. If B is changing at the rate of dB/dt, the emf that is produced by the changing magnetic field is `xi` here p = `sqrt(R^(2) - ((l)/(2))^(2)) `. then

Options

A. The magnitude of the electric field created is `(1)/(2)r(dB)/(dt)`
B. The magnitude of the electric field component along the length of the rod is `(1)/(2)p (dB)/(dt)`
C. The magnitude of the electric field component perpendicular to the rod is zero
D. The induced emf is `(1)/(2)"lp" (dB)/(dt)`.

Answer

A, B, C, D
