JEE MainPhysicsModerateCapacitance

The charge that will flow to earth when only switch S1 is closed
and right most plate is uncharged is

Show answer and solution
At point D,E→\overrightarrow{E}must be zero because potential
of left most plate is zero.

So, x = 0

E→A=0{\overrightarrow{E}}_{A} = 0 (Conductor)
x = y + Q

y = - Q
