Two insulating sm
Answer :
Given,
Electric force between the two spheres,
Distance between the two spheres,
We know that, magnitude of charge on electron,
Let n electrons be transferred from one sphere to another. Then, charge on one sphere is +ne and the other is -ne.
________________________________________________
Formula used:
By Coulomb’s law, the electric force is given by:
Where ϵ0 is the permittivity of free space
k is the electrostatic constant
q1 and q2 are the magnitude of charges
r is the distance of separation between the charges
__________________________________________________
The magnitude of electric force is given by:
Hence, about electrons are transferred.
