The transformer described in the book (consisting of coils on opposite sides of a toroidal core) is modified as follows: A slot is cut through the core on the secondary side, and the secondary coil is rewound through the slot. As a result, the secondary coil remains oriented in the same direction relative to the magnetic flux, but has exactly one-half the cross-sectional area as it did previously (i. e., is now one-half the cross-sectional area of the primary coil). The overall cross-sectional dimensions of the core remains nearly the same on both sides, so the flux density in the core is not significantly affected. The number of turns in the primary and secondary coils are 200 and 300, respectively. What is the potential V2 on the secondary side in terms of the potential V1 on the primary side
