A circular coil of radius

10\,\text{cm}

is placed in a uniform magnetic field of

0.30\,\text{T}

. The field makes an angle of

60^{\circ}

with the normal to the coil. The magnitude of magnetic flux through the coil is closest to (a)

9.4\times10^{-3}\,\text{Wb}

(b)

4.7\times10^{-3}\,\text{Wb}

(c)

2.4\times10^{-3}\,\text{Wb}

(d)

1.9\times10^{-2}\,\text{Wb}
