The magnitude of the electrostatic force between two identical ions that separated by a distance of `10.0 xx 10^(-10)m` is `9.25 xx 10^(-10)N`. (a) What is the charge of each ion ? (b) How many electrons are "missing" from each ion (thus giving the ion its charge imbalance) ? (c ) What is the force magnitude if the separation is halved ?

Explanation

(a) `3.2 xx 10^(-19) C`, (b) 2, (c ) `3.7 xx 10^(-9) N`
