Electromagnetic Induction

A coil 10 turns and a resistance of \(40 \Omega\) is connected in series with B.G. of resistance \(30 \Omega\). The coil is placed with its plane perpendicular to the direction of a uniform magnetic field of induction \(10^{-2} \mathrm{~T}\). If it is now turned through an angle of \(60^{\circ}\) about on axis in its plane. Find the charge indicted in the coil. (Area of a coil \(=10^{-2} \mathrm{~m}^2\) )
