A glass rod that has been charged to + 19.0 nC touches a metal sphere. Afterward

Question

A glass rod that has been charged to + 19.0 nC touches a metal sphere. Afterward, the rod's charge is + 2.0 nC. What kind of charged particle was transferred between the rod and the sphere, and in which direction·>> That e. did it move from the rod to the sphere or from the sphere to the rod? Electrons, from the sphere to the rod Electrons, from the rod to the sphere Protons, from the sphere to the rod Protons, from the rod to the sphere How many charged particles were transferred' Express your answer using two significant figures.

Explanation / Answer

we know that charge particles are electrons

since total charge transferred is 2 x10^-9 C

charge of each electron is 1.6 x 10^-19 C

Let total number of electrons transferred is N

so we have

N x 1.6 x 10^-19 = 2 x 10^-9

N = 1.25 1 10^10 ( answer )
