According to Appendix C of the text, M= 5.98 ×1024kg, and m= 7.36 ×1022kg, so (using 4πε0= 1/k) the charge is q=×⋅××=×−6 67 107 36 10598 10899 1057 10112224913.....N m kgkgkgNm CC.22chch(b) The distance rcancels because both the electric and gravitational forces are proportional to 1/r2. (c) The charge on a hydrogen ion is e= 1.60 ×10–19C, so there must be 1332195.7 10 C3.6 10 ions.1.6 10Cqne−×=== ××Each ion has a mass of im=1.67 ×10–27kg, so the total mass needed is ()
