Final answer:
The net charge of the system after adding five electrons to 1.0 C of positive charge remains approximately 1.0 C, as the negative charge of the electrons is negligible compared to the initial positive charge.
Step-by-step explanation:
The student has asked what the net charge of the system would be after adding five electrons to 1.0 C of positive charge. The charge of one electron is –1.602 x 10–19 C. Therefore, the total negative charge contributed by five electrons is 5 x (–1.602 x 10–19 C) = –8.01 x 10–18 C. When this charge is added to 1.0 C, the net charge becomes 1.0 C - 8.01 x 10–18 C, which is approximately 1.0 C since the charge of the electrons is significantly smaller in magnitude compared to 1.0 C and can be considered negligible.
