SUMMARY
To calculate Pat's weight at an altitude twice the radius of the Earth, use the gravitational force formula Fg = G(m1)(m2)/r^2. Given Pat's mass of 65.5 kg, the gravitational acceleration at this altitude is reduced due to the increased radius, resulting in a weight of 71.4 N. The gravitational constant G is 6.67 x 10^-11, and the standard gravitational acceleration g at Earth's surface is 9.8 m/s². Understanding how gravitational force changes with distance is crucial for solving this problem.
