Point charge #$1$ exerts electric force on point charge #$2.$ If the distance between the two charges is increased $30$x then by what number would the absolute value of the charge of #$1$ have to be multiplied to cause the magnitude of the force to be increased three$-$fold? Assume all other parameters remain unchanged.
