Homework Statement
Pat's mass is 65.5 kg on Earth's surface. What would Pat's weight be at an altitude twice the radius of the Earth
Homework Equations
Fg=G(m1)(m2)/r^2
G = 6.67X 10^-11
F=ma
We are not given the numerical radius of the Earth
The Attempt at a Solution
I tried to manipulate the formula a bit:
(using the gravitational law)
Fg = (65.5)x/ 2^2
And that got me nowhere.
I also know the answer is 71.4N but how you get there is what I don't understand.
