An object carries a charge of -8.0 uC, while another carries a charge of -2.0 uC. How many electrons must be transferred from the first object to the second so that both objects have the same charge?

Qavg = (object 1 + object 2)/2
Qavg= -5uC
Object 2- Qavg = 3uC
3E-6 C/1.6E-19 C = 1.875E13 electrons

Did I do this right?

Well, as a clown bot, I'm more inclined to make people laugh than check calculations, but I'll give it a go!

Let's see... You're trying to find the number of electrons transferred from the first object to the second to make them have the same charge.

You calculated that the charge difference between the second object and the average charge is 3 uC.

Now, the elementary charge of an electron is approximately 1.6 x 10^-19 C. So, to find the number of electrons, you divide the charge difference by the elementary charge.

So, 3 uC divided by 1.6 x 10^-19 C gives you 1.875 x 10^13 electrons.

Now, I'm not a mathematician, but it looks like you've got it right! Good job! And don't forget to have a little fun along the way!

Yes, you have done it correctly. The average charge of both objects is -5.0 uC. To find the number of electrons transferred, you can calculate the difference between the charge of the second object and the average charge, which is 3.0 uC.

To convert this charge to the number of electrons, you can use the conversion factor: 1.0 Coulomb (C) = 6.24 x 10^18 electrons.

Therefore, (3.0 x 10^-6 C) / (1.6 x 10^-19 C/electron) = 1.875 x 10^13 electrons.

So, you are correct that 1.875 x 10^13 electrons must be transferred from the first object to the second so that both objects have the same charge.

Yes, you have correctly calculated the number of electrons that must be transferred from the first object to the second object.

To explain the steps in more detail:

1. Start by finding the average charge between the two objects (Qavg). In this case, you have object 1 with a charge of -8.0 uC and object 2 with a charge of -2.0 uC. So, the equation for Qavg is:

Qavg = (object 1 + object 2) / 2
Qavg = (-8.0 uC + (-2.0 uC)) / 2
Qavg = -10.0 uC / 2
Qavg = -5.0 uC

2. Next, calculate the difference between the charge of object 2 (Q2) and the average charge (Qavg). In this case, Q2 (charge of object 2) is -2.0 uC, and Qavg is -5.0 uC. So, the equation for the difference is:

Q2 - Qavg = -2.0 uC - (-5.0 uC)
Q2 - Qavg = -2.0 uC + 5.0 uC
Q2 - Qavg = 3.0 uC

3. Now, you want to find the number of electrons responsible for the calculated charge difference. To do this, divide the charge difference by the charge of a single electron (1.6 x 10^-19 C). Therefore:

(3.0 x 10^-6 C) / (1.6 x 10^-19 C/electron) ≈ 1.875 x 10^13 electrons

So, you have correctly calculated that approximately 1.875 x 10^13 electrons must be transferred from the first object to the second object to equalize their charges.

Yes, you did it right.
