A coil of

200

turns encloses an area of

20\,\text{cm}^2

. It is placed in a uniform magnetic field of

0.05\,\text{T}

such that the angle between the field and the normal to the coil is

30^{\circ}

. The total magnetic flux linked with the coil is (a)

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

(b)

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

(c)

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

(d)

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