Among the following the charge that does not exist on any type of charged body is
Options
- A3.2 10⁻¹⁹ C
- B6.4 10⁻¹⁹ C
- C9.6 10⁻²⁰ C
- D9.6 10⁻¹⁸ C
Correct answer
C. 9.6 10⁻²⁰ C
Step-by-step solution
Charge on any body must be an integral multiple of charge on an electron or proton, i.e., charge is quantized, Q = ne If Q=9.6 10⁻²⁰ than, n = Q e = 9.6 10⁻²⁰ 1.6 10⁻¹⁹ =0.6 It is not a number, thus this charge does not exists.
