a. A metal ring was tom by Coulomb forces when the ring charge was equal
to Q. They made exactly the same new ring, but from a material that is ten
times stronger. What kind of charge will break the new ring?
b. What kind of charge will break a new ring made of the same material, if
all the dimensions of the new ring are three times the size of the old one?
