Homework Statement
I am a physics tutor. I want to show the relationship between electric charges and forces and gravitational forces. I am relating an example as follows.
If we have a hollow metal sphere the size of the Earth with a charge of 1.63E15 C and a piece of tinfoil the surface with a charge of only 2.72E-9 C , the tinfoil would weigh the same as a 250 pound (986 N) person. So I am wondering..
How much charge can you get if you rubbed a glass rod with fur, i.e. how many coulombs. If I rubbed the glass rod with fur, would it be to heavy to hold?
Just wondering.
