Then its quiet simple.
 
See earliar also i explained that metals have infinite dielectric constant.
 
So here the capacitance is the resultant of series combination of C1 and C2. Say Ceff
 
Here C1 = capacitance of the unfilled region = C/2
 
C2 = Capactance of the region filled with metallic slab =
 
So Ceff = C1 x C2 / (C1 + C2)
 
Under the limiting case when  C2 tends to  
 
 Ceff = C1 = C/2
The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp.
