358689 If a coil of 40 turns and area \(4.0\;\,c{m^2}\) is suddenly removed from a magnetic field, it is observed that a charge of \(2.0 \times {10^{ - 4}}\,C\) flows into the coil. If the resistance of the coil is \(80 \Omega\), the magnetic flux density in \(Wb/{m^2}\) is:
358690 A long solenoid of diameter \(0.1\;\,m\) has \(2 \times 10^{4}\) turns per meter. At the centre of the solenoid, a coil of 100 turns and radius \(0.01\,\;m\) is placed with its axis coinciding with the solenoid axis. The current in the solenoid reduces at a constant rate to \(0\;A\) from \(4\;A\) in \(0.05\;s\). If the resistance of the coil is \(10 \pi^{2} \Omega\). The total charge flowing through the coil during this time is :-
358691 A thin circular ring of area \(A\) is perpendicular to uniform magnetic field of induction \(B\). A small cut is made in the ring and a galvanometer is connected across the ends such that the total resistance of the circuit is \(R\). When the ring is suddenly squeezed to zero area, the charge flowing through the galvanometer is
