Imagine two 2.5g bags of protons, one at the earth's north pole and the other at the south pole.

How many protons are in each bag?
Calculate the gravitational attraction that each bag exerts on the other.
Calculate the the electrical repulsion that each bag exerts on the other.
Is the gravitational force in part B large enough for you to feel if you were holding one of the bags?
Is the electrical force in part C large enough for you to feel if you were holding one of the bags?
