Question

What is the range of charges involved in common static electricity?

1) Nanocoulombs to microcoulombs
2) Picocoulombs to millcoulombs
3) Microcoulombs to millicoulombs
4) Nanocoulombs to picocoulombs

Answer 1

The common static electricity involves charges ranging from nanocoulombs to microcoulombs. Around 1.25 x 10^10 electrons are needed to form a charge of -2.00 nC, and approximately 3.13 x 10^12 electrons must be removed from a neutral object to create a net charge of 0.500 μC.

Step-by-step explanation:

The range of charges involved in common static electricity is from nanocoulombs to microcoulombs. To answer the questions:

1. To find out how many electrons are needed to form a charge of -2.00 nC, we use the charge of a single electron, which is approximately -1.60 x 10-19 coulombs. Thus, the number of electrons (n) would be: n = total charge / charge of one electron, which gives n = -2.00 x 10-9 C / -1.60 x 10-19 C/electron = 1.25 x 1010 electrons.
2. To find out how many electrons must be removed to leave a net charge of 0.500 μC, the same calculation applies: n = 0.500 x 10-6 C / 1.60 x 10-19 C/electron = 3.13 x 1012 electrons must be removed.
