6. how long would it take an object to fall a distance of 100 m on Jupiter compared to the Earth ?As an indication of the size of the sun's gravitational pull on the Earth, suppose that the sun's gravitational attraction could be replaced by a steel wire running from the sun to the Earth, with the wire's tension holding the Earth in it's orbit. Good steel has a breaking stress of 5.0 x 10# N/m/m. a. Calculate the cross-sectional area of the wire that could just hold the Earth in it's orbit b. Calculate the corresponding wire diameter
