Three metallic plates out of which the middle is given charge \( Q \) as shown in the figure. The outer plates can be earthed with the help of switches \( S_{1} \) and \( S_{2} \). The area of each plates is the same. Answer the following question \( \frac{1}{\overline{=}} \) based on the given passage.
The charge appearing on the outer surface of extreme left plate is
(1) \( -(Q / 2) \)
(2) \( (Q / 2) \)
(3) \( Q \)
(4) \( -Q \)
