Question

Two positive ions, each carrying a charge q, are separated by a distance d. If F is the force of repulsion between the ions. the number of electrons missing from each ion will be (e being the charge on an electron)

Answer 1

Correct option  (c)

Explanation:

According to Coulomb's law, the force of repulsion between the two positive ions each of charge 4, separated by a distance d is given by

Since, q = ne

n = number of electrons missing from each ion

e = magnitude of charge on electron
