Consider the situation of the given figure . If `1.0muC ` is placed on the upper plate , what will be the potential difference between (a ) the upper and middle plates and (b ) the middle and the lower plate? If capacitance of each capacitor is 50 nF.

Explanation

Here given , Capacitance of each capacitor
` C = 0.05 xx 10^(-6) F`
charge `q = 1 mu C `
which is given upper palte `= 5 mu C ` of charges appear on the outer and inner side of the upper plate and ` 5 mu C` of charge also seen on the middle
(a) charge of each plate `= 5mu C`
Capacitance `= 0.05 mu F `
`rArr v = 10 V `
(b) The charge of lower plates is also equal to` 0.5 mu C `
`B = 10V`
The potential is 10V .
