A three-phase load is connected to a three-phase balanced supply as shown in the figure. If $V_{an}=100\angle0^\circ\;$ V ,$V_{bn}=100\angle-120^\circ\;$ V and $V_{cn}=100\angle-240^\circ\;$ V  (angles are considered positive in the anti-clockwise direction), the value of R for zero current in the neutral wire is ___________$\Omega$ (up to 2 decimal places).
