Earth's radius. Calculate how much more or less you would weigh on this planet

compared to your weight on Earth. Express your answer as a factor or fraction of

your weight on Earth. Show all work.

g , and the weight, are proportional to M/R^2

M/R^2 is 4Me/(16 Re^2) = (1/4) Me/Re^2

on the new planet.

Me = earth mass

Re = earth radius

Weight will be four times less on the new planet

**drwls**, Sunday, October 2, 2011 at 10:44amThe "M" in the first equation is the object mass, not the earth mass. I should have used m.

The answer is the same
