The Coil Shown in the Figure Has 2 Turns, a Cross-Sectional

The coil shown in the figure has 2 turns, a cross-sectional area of 0.20 m2, and a field (parallel to the axis of the coil) with a magnitude given by B = (4.0 + 3.0t2) T, where t is in s.What is the potential difference, VA -VC, at t = 3.0 s?

A) (-7.2 V)
B) +7.2 V
C) (-4.8 V)
D) +4.8 V
E) (-12 V)
