objects that are flying around (like sand in a dust storm) can become electrically charged. how much charge these objects accumulate varies, but a reasonable scale is pc (10-12 coulombs). if a grain of sand has a net charge of 59pc, approximately how many electrons has it lost?

Respuesta :

The number of electrons lost is 3.69 * 10^8 electrons

What is the number of electrons lost?

We know that charge that is carried by an electron has the magnitude of 1.6 * 10^-19C. In this case we have been asked to obtain the number of electrons that could be lost in the process and we have the charge as 59pc.

Knowing that;

Q = ne

Q = magnitude of charge

n = number of electrons

e = magnitude of charge on an electron

n = Q/e

n = 59 * 10^-12/1.6 * 10^-19C

n = 3.69 * 10^8 electrons
