Notes:
• Temperatures are in Kelvin (-273.15◦ C equals 0K).
• The Coulomb’s constant equals ke = 8.99 × 109 N m2 /C 2 .
• The gravitational constant equals G = 6.674 × 10−11 m3 /kg s2 . Acceleration due
to the Earth’s gravity can be assumed to equal g = 9.81 m/s2 .
• If other constants are required, they will be provided in the question.
