Here three capacitor are formed and each has area
` A = 96 / eplison_0 xx 10^(-12) F -m`
`d = 4 mm `
`= 3 xx 10^(-3) m `
Capacitance of capacitor
` C = 24 xx 10^(-9) F`
As three capacitors are arranged in series
` C = 8 xx 10^(-9) `
The total charge to a capacitor
` = 8 xx 10^(-9) xx 10 `
`= 8 xx 10^(-8) `
The charge of a single plate
` = 2 xx 8 xx 10^(-8)`
`= 16 xx 10^(-8) = 0.16 mu C` .
