Consider the gaussian surface the induced charge be as show in the fig. [in the quest.]the net field at p due to all the charge is zero 


-2Q+q/2Ae0 (left)+q/2Ae0


+q-Q+q=0


q=3/2Q


charge on the right side of right most plate


=-2Q+q=-2Q+3/2Q


=-Q/2


and this is the solution and if u hve any other doubt about physics and contact me http://www.facebook.com/madhav.purohit.984
