How many electrons have been removed from a positively charged electroscope if it has a net charge of 6x10-11?


pls help !!!

Answer :

How much negative charge has been removed from a positively charged electroscope if it has a charge of 7.5x10-11C?

If C is Coulombs then, −1 C is equivalent to the charge of approximately 6.242×10^18 electrons.

You already gave the answer: -7.5x10–11C

It is like asking: What colour is my white horse?

Now if you want to know how many electrons have been removed, then multiplying the number of electrons in a coulomb by the coulombs you have, you get 4.6815 x 10^8 electrons. Which is almost the same answer as before.

3.7 x 10^8 electrons are removed from a positively charged electroscope.

The magnitude of charge carried by one electron is 1.602 x 10^-19 C

From the question, we can see that the net charge on the electroscope is 6 x 10^-11 C

Given that;

6 x 10^-11 = 1.602 x 10^-19 n

Where n is the number of electrons removed from a positively charged electroscope

Therefore;

n = 6 x 10^-11/ 1.602 x 10^-19

n = 3.7 x 10^8 electrons
