A large airtight container is segmented into two compartments and in the first compartment there are 5000 electrons and the in the second compartment there are 2500 protons. Assuming electrons and protons recombine with one another, what will be the total charge of the assembly some time after the partition has been removed?

Step 1

According to this problem, in the first compartment of the container, 5000 electrons are present and in the second compartment of the container, 2500 protons are present.

Since the electrons and the protons recombine with one another, when the partition between the compartments is removed, 2500 protons will recombine with 2500 electrons and thereby reducing the number of electrons remaining to be equal to 2500.

Step 2

Now, the electrons are negatively charged particle and charge of an electron can be expressed as
