Aglass rod is charged to 6.0 nc by rubbing. how many electrons have been removed or protons added

n = 3.75 x 10¹⁰ electrons.

Explanation:

given,

Charge on the glass rod = 6 n C

In the given question the electron is removed because proton never moves.

We know

Charge of 1 electron = 1.6 x 10⁻¹⁹ C

x number  of electron have charge  = 6 x 10⁻⁹ C

now,

n × 1.6 x 10⁻¹⁹ C = 6 x 10⁻⁹ C

where n is the number of electron

n = 3.75 x 10¹⁰ electrons.

number of electron moved is equal to n = 3.75 x 10¹⁰ electrons.

3.75 x 10^10

Explanation:

charge, q = 6 nC = 6 x 10^-9 C

Charge of one electron, e = 1.6 x 10^-19 C

Number of electrons removed = total charge / charge of one electron

n = (6 x 10^-9) / (1.6 x 10^-19)

n = 3.75 x 10^10

Thus, the number of electrons removed is 3.75 x 10^10.

coil wire, increase current, put iron inside the coil

that would be because of both gravity and friction. so     c
