Class 12 NEET Physics Electrostatics Questions Part 1

According to Coulomb’s law, the force of repulsion between the two positive ions each of charge q, separated by a distance d is given by

q=√4πε0Fd2...........(i)
Since, q=ne
Where, n = number of electrons missing from each ion
   e = magnitude of charge on electron
∴n=

q

e

=√

4πε0Fd2
