Members of the Star Trek exploration committee find themselves on Physitopia, a planet with its own unique gravitational characteristics. The Force-sensitive individuals on the committee, accustomed to manipulating the Force on various planets, are now faced with a new challenge: understanding and adapting to the gravitational force on Physitopia. Physitopia has a mass of 6.46 × 1023 kg and a radius of 3.39 × 106 m, poses an intriguing gravitational scenario. To address the concerns of the Star Trek characters, we must calculate the acceleration due to gravity on Physitopia and determine the weight of a 65 kg individual.
With density Y1(unit: kg/m), 3 endless wires are just above the x,y,z axes.
Find the gravitational field at (x,y,z) position.
NOTE: Give your answer in terms of (x,y,z, ^x, ^y, ^z(unit vectors), G, Y1)
A hint is given in the figure.

According to the story, as the capsule approaches Earth's center, the gravitational force on the explorers becomes alarmingly large and then, exactly at the center, it suddenly but only momentarily disappears. Then the capsule travels through the second half of the tunnel, to the north pole. With what speed would mail pass through the center of Earth if falling in this tunnel? Ignore air resistance.
