Question

Si un cuerpo adquiere una carga de -0,02 C, ha ganado o ha perdido electrones? Cuantos?

Answer 1

Question :

If a body acquires a charge of -0.02 C, has it gained or lost electrons? Many?

Solution :

We know, charge gained is shown by negative sign.

Since, charged acquired is given as -0.02 C .

Therefore, it is body has gained electrons.

Now, number of electrons is given by :

`n = (net\ charge)/(charge \ on \ one \ electron)\\\\n = (-0.02)/(-1.60 * 10^(-19))\\\\n = 1.25* 10^(17)`

Hence, this is the required solution.
