$\backslash (\backslash$mathrm$\{$A$\}10\backslash$mu $\backslash$mathrm$\{$C$\}\backslash )$ charge is at the origin. A $-\backslash (15\backslash$mu $\backslash$mathrm$\{$C$\}\backslash )$ charge is on the x $-$axis $10$ cm to the right of the origin. At what point other than at infinity can a $\backslash (1\backslash$mu $\backslash$mathrm$\{$C$\}\backslash )$ charge be placed so that there will be no net electrostatic force on it$?$

Multiple Choice

at one point on the $\backslash ($ x $\backslash )-$axis to the left of the positive charge

at some point off the $\backslash ($ x $\backslash )-$axis either above or below

at one point between the two charges

at one point on the $\backslash ($ x $\backslash )-$axis to the right of the negative charge

at no point
