Solution

Step 1: Explanation of Charge

  1. A charge is a characteristic property of a body.
  2. It can be determined by evaluating the number of electrons present or absent in this body.
  3. The presence of excess electron causes the body to be negatively charged, while the absence of excess electron causes the body to be positively charged.
  4. The fundamental value of the charge is 1.6×10-19C.

Step 2: Evaluate the net charge on the body

  1. We know that for a neutral atom, the number of electrons is equal to the number of protons.
  2. Here we have a body containing n1 electrons and n2 protons.
  3. We know that electrons are negatively charged, and protons are positively charged.
  4. Hence, the net charge in this body can be given as n2-n1

Hence, the total amount of charge on the body is n2-n1.
