In a vibration magnetometer, the time period of a bar magnet oscillating in horizontal componnt of earth\'s magnetic field is `2 sec`. When a magnet is brought near and parallel to it, the time period reduces to `1 sec`. The ratio `H//F` of the horizontal component `H` and the field `F` due to magnet will be
