The mass of the balls has a charge of 0.96 nC. Determine how many electrons are missing on it.

It is known from the problem statement that the ball has a charge of 0.96 nC.

First you need to remember the formula for the charge of an electron.

It looks like this: e = 1.6 * 10-19 Cl.

Thanks to this formula, you can calculate the number of electrons that the ball is missing. Let’s use the corresponding formula: N = q / e.

Now that the formula is known, we substitute all known values and find the number of missing electrons.

0.96 * 10-9 / 1.6 * 10-19 = 6 * 10-19 – the missing number of electrons.

Answer: just 6 * 10-19 electrons are missing.
