154841 Two coaxial solenoids are made by winding thin insulated wire over a pipe of crosssectional area $A=10 \mathrm{~cm}^{2}$ and length $=20 \mathrm{~cm}$. If one of the solenoid has 300 turns and the other 400 turns, their mutual inductance is $\left(\mu_{0}=4 \pi \times 10^{-7} \mathbf{T m A}^{-1}\right)$
154842 A coil 10 turns and a resistance of $20 \Omega$ 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 an axis in its plane. Find the charge induced in the coil. (Area of a coil $=10^{-2}$ $\mathbf{m}^{2}$ )
