There are two planets. planet 1 is three times the mass of planet 2. however, a person standing on the surface of planet 2 experiences a force that is 12 times stronger than on planet 1. how is this possible? explain in terms of physics phenomena and terminology.

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
