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

Options

A. `(4piepsilon_(0)Fd^(2))/(e^(2))`
B. `(4piepsilon_(0)Fd^(2))/(e^(2))`
C. `sqrt((4piepsilon_(0)Fe^(2))/(d^(2)))`
D. ` sqrt((4piepsilon_(0)Fd^(2))/(e^(2)))`

Answer

D

Explanation

`F = (("ne")^(2))/(4piepsilon_(0)d^(2)) rArr n = sqrt((4piepsilon_(0)Fd^(2))/(e^(2)))`
