The capacitance between the adjacent plates shown in figure is `50 nF` . A charge of `1.0muC `is placed on the middle plate (a )What will be the charge on the outer surface pf the upper plate ? (b ) Find the potential difference developed between the upper and the middle plates .

Explanation

(a) when charge of `1 mu C is introduced to the B plate, We also get a ` 0.5 mu C ` charge on the upper surface of plate A
(b) Given, ` C = 50 mu F = 50 xx 10(-9) F `
`= 5 xx 10^(-8) F `
Now charge `= 0.5 xx 10^(-6) C `
`v= 10V` .
