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)A. `(4 pi in_(0) Fd^(2))/(q^(2))`B. `(4pi in_(0) Fd^(2))/(2)`C. `sqrt((4 pi in_(0) Fe^(2))/(d^(2)))`D. `sqrt((4pi in_(0) Fd^(2))/(e^(2)))` |

Answer» Correct Answer - 4 `F = (1)/(4 pi in_(0)) .(q^(2))/(d^(2))` `q = n e = sqrt(4 pi in_(0) d^(2) F)` `n = sqrt((4 pi in_(0) d^(2) F)/( e))` `n`: number of missing electrons. |
