After rubbing the glass rod, its charge became equal to 3.2 μC. How many electrons were removed

After rubbing the glass rod, its charge became equal to 3.2 μC. How many electrons were removed from the stick by friction.

Problem data: q (charge received on a glass rod) = 3.2 μC (3.2 * 10 ^ -6 C).

Constants: e (electron charge) = -1.6 * 10 ^ -19 C.

The number of electrons removed from the glass rod is determined by the formula: n = q / e.

Let’s do the calculation: n = 3.2 * 10 ^ -6 / (1.6 * 10 ^ -19) = 2 * 10 ^ 13 electrons.

Answer: 2 * 10 ^ 13 electrons were removed from the glass rod during friction.
