Answer 1

Answer #1

an electron has a charge of: q = -1.6*10^-19 C.

-58 uC of charge:

[(1 electron)/(-1.6*10^-19 C)]*[-58*10^-6 C ]

= 38.6*10^13 excess of electrons.

The rug was neutral before you walked on it. Now that you picked up an excess of :

-58 uC

The rug now has a positive charge of:

+58 uC
