Homework Statement
A person on Earth weighs 750N. What would the person weigh on a planet with 1.2 times the radius and 1.9 times the mass?
Homework Equations
mg=Gmme/re2
The two ms cancel, leaving:
g=Gme/re2
The Attempt at a Solution
Since the two ms cancel out, I thought that the most logical way to approach the problem would be to take the equation g=Gme/re2 and the values I was previously given for the Earth's radius and mass, multiply by the factors given,and solve the problem.
g=(6.67*10-11)(1.1362*1024) /7656000
g=98981121.21 N
The answer seems too large. Did I miss a step, was my logic flawed, or am I just overthinking the answer?
Thanks so much.
