I would need more electrons 1.3125 10¹⁰ electrons

Explanation:

Static electricity is formed by induced charges in each part of the system, so the net charge does not change.

Let us analyze the situation presented, if the carpet acquires a positive charge, so that it does not alter the total charge in man, it should acquire a negative charge, to have a net negative charge I would need more electrons that have a negative charge.

We can know the number of electrons by a rule of proportions, if an electron has a charge of 1.6 10-19 C for a charge of 2.15 10-9 C how many electrons are needed

# = 2.15 10⁻⁹ / 1.6 10⁻¹⁹

# = 1.3125 10¹⁰ electrons

The number is very high for which we will not worry about rounding since the number of electrons must be an integer
