What is the main topic of the video?

The main topic is solving a problem related to electric charge involving protons and electrons.

How is the electric charge calculated?

The electric charge is calculated by subtracting the number of electrons from the number of protons.

What can be determined from the number of protons and electrons?

If there are more protons than electrons, the object is positively charged; if there are more electrons, it is negatively charged.

What is the value of the elementary charge used in the calculations?

The value of the elementary charge is +1.6 x 10^-19 C for protons and -1.6 x 10^-19 C for electrons.

What is the final conclusion of the problem?

The object is positively charged with a net charge of 1.6 C.
