Charge on electron is
Options
- A3.2 10⁻¹⁹ C
- B1.6 10⁻¹⁹ C
- C-1.6 10⁻¹⁹ C
- D-3.2 10⁻¹⁹ C
Correct answer
C. -1.6 10⁻¹⁹ C
Step-by-step solution
The elementary charge e is the fundamental physical constant representing the electric charge carried by a single proton. The charge of an electron is defined as -e . The value of the elementary charge is approximately 1.602 10⁻¹⁹ C . Therefore, the charge on an electron is -1.6 10⁻¹⁹ C . Answer: -1.6 10⁻¹⁹ C
