Consider an \(HCl\) molecule, where one of its electrons is located exactly midway between the two nuclei, at a given instant. Ignore all the other electrons and any quantum effects.

Let \(\vec F_H\) be the electrostatic force exerted by the electron on the \(H\)-nucleus and \(\vec F_{Cl}\) be the force exerted by the electron on the \(Cl\) nucleus. Then:

1.	\(|\vec F_{Cl}|=|\vec F_H|\)and \(\vec F_{Cl}\) is opposite to \(\vec F_H\)
2.	\(|\vec F_{Cl}|=|\vec F_H|\)and \(\vec F_{Cl}\) & \(\vec F_H\) are in the same direction
3.	\(|\vec F_{Cl}|>|\vec F_H\) and \(\vec F_{Cl}\) is opposite to \(\vec F_H\)
4.	\(|\vec F_{Cl}|<|\vec F_H|\) and \(\vec F_{Cl}\) is opposite to \(\vec F_H\)
