Question

Usted arrastra los pies sobre un piso alfombrado en un día seco y la alfombra adquiere una carga positiva neta. a) Usted a deficiencia o 2) un exceso de electrones? b) Si la carga adquirida tiene una magnitud de 2.15 nC, (cuántos tendrá I) un electrones se transfirieron?

Answer 1

Answer:

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
