A copper ring having a cut such as not to form a complete loop is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring as shown in figure. The acceleration of the falling magnet is ( g= acceleration due to gravity)

Step-by-step solution

Analysis of Magnet Falling Through Cut Ring When a magnet falls through a conducting ring, Faraday's law indicates that a changing magnetic flux induces an electromotive force. For a current to flow, however, the circuit must form a closed loop. Since the copper ring has a cut, it cannot sustain an induced current. Without current, no opposing magnetic field is generated via Lenz's law. The magnet experiences only gravitational acceleration, g , as no electromagnetic force opposes its motion. Thus, the correct choi
