Answer:
Number of electrons, n = 12 electron
Explanation:
Given that,
The distance between charged spheres,
The object experiences an electrostatic force that has a magnitude of,
The electric force between spheres is given by :
Let there are n number of electrons. Using quantization of electric charge we get :
n = 11.93 electrons
or
n = 12 electrons
Hence, 12 electrons produce the charge on one of the objects.
