FREE Expert Solution

We are being asked to calculate the number of electrons acquired when the body develops a charge of -14 microcoulomb.


RecallThe attractive and repulsive forces between charged particles can be explained by Coulomb’s Law.

We can use Coulomb's law and apply the following formula to solve the problem:

Q = n×e

where: 

Q is the charge in Coulomb

n is the number of electrons

e is the electronic charge = -1.60x10-19 Coulomb per electron
