Question

Two balloons have equal and opposite charges. Balloon one has n = 108 excess electrons. The balloons are separated by d = 2.9 m and each electron has a negative charge of e = 1.602 × 10⁻¹⁹ C. What is the total charge on balloon one?

Answer 1

The total charge on balloon one with 108 excess electrons is 1.7296 × 10⁻¹⁷ C, with each electron contributing 1.602 × 10⁻¹¹ C to this negative charge.

Step-by-step explanation:

The total charge on balloon one, which has n = 108 excess electrons, can be calculated by multiplying the number of excess electrons by the charge of a single electron (e = 1.602 × 10⁻¹¹ C). Therefore, the total charge on balloon one is 108 × 1.602 × 10⁻¹¹ C, which equals 1.7296 × 10⁻¹⁷ C. The minus sign indicates that it is a negative charge due to the negative charge carried by electrons.
