Question

Common static electricity involves charges ranging from nanocoulombs to microcoulombs. How many electrons must be removed from a neutral object in order to leave a net charge of 9.7 μC?

Answer 1

6.0625 x 10^13

Step-by-step explanation:

Charge of one electron, e = 1.6 x 10^-19 C

Total charge, Q = 9.7 μ C = 9.7 x 10^-6 C

The number of electrons is given by

n = Total charge / charge of one electron

n = Q / e

n = (9.7 x 10^-6) / (1.6 x 10^-19)

n = 6.0625 x 10^13
