1. A 78.0 kg man weighs himself at the north pole and at the equator. Which scale reading is higher? By how much? 2. I think that this has to do with with the radius being different at the north pole and equator, which would cause different centripetal accelerations. So I assume I'm supposed to find the net force on the man in both places. 3. I'm lost on how to visualize this. A man on the north pole, on the very top of the axis, isn't in circular motion at all, except around the sun, ,right? Any help, much appreciated.
