Q135

Which one of the following is NOT a basic property of electric charge ?

  1. (a) Charges can be added
  2. (b) Charge is conserved
  3. (c) Charge on a body is always an integral multiple of an electron or a proton charge
  4. (d) Charges can be created and destroyed in an isolated systemCorrect answer

Solution.

Answer: (d) Charges can be created and destroyed in an isolated system

  1. The total charge of an isolated system is conserved: it can be neither created nor destroyed.
  2. Charges are additive, and charge on a body is a whole-number multiple of the electron's charge.
  3. So (d) is the statement that is not a property of charge.
