(a) By what distance do two objects carrying \(1.0 \mathrm{C}\) of charge each have to be separated beforc the electric force exerted on each object is \(1.0 \mathrm{~N}\) ?

(b) How much charge should be placed on each of two small objects separated by \(1.0 \mathrm{~m}\) so that the electric force exerted on cach is \(1.0 \mathrm{~N}\) ?
