Question

A neutral object develops an electric charge when it either gains or loses electrons

True or false ?

Answer 1

True

Step-by-step explanation:

A neutral object is an object whose net charge is zero, so the sum of the positive charges is equal to the sum of negative charges:

`Q=Q_(pos)+Q_(neg)=0\\Q_(pos) = -Q_(neg)`

If the neutral object develops an electric charge (= different from zero), it means that this balance has changed. In particular, usually electric charge is carried by electrons (negative charges), so the object has either gained or lost electrons.

In particular:

- if the object has gained electrons, it has became negatively charged

- If the object has lost electrons, it has became positively charged
