A circular coil of radius 10 cm, 500 turns and resistance 2 Ω is placed with its plane, perpendicular to the horizontal component of the earth’s magnetic field. It is rotated about its vertical diameter through $$180^\circ$$ in 0.25s. The induced e.m.f in the coil is (Take $$H_E = 3.0 \times 10^{-5} T$$)

A

$$6.6 \times 10^{-4} V$$

B

$$1.4 \times 10^{-2} V$$

C

$$2.6 \times 10^{-2} V$$

D

$$3.8 \times 10^{-3} V$$
