Both the cacpacitors shown in figure  are made ofsquare of edge a The separations between the plates of the capacitors are d_1and d_2as shown in the figure A potential difference V is applied between the point a and b .An electron  is projected between the plate s of the upper capacitor along the central line . With what minimum speed should the electron be projected so that it is does not collide with any plate ? consider only the electric forces.
