Q.

Two large plane parallel conducting plates are kept 10 cm apart as shown in figure. The potential difference between them is V. The potential difference between the points A and B (shown in the figure) is:          [2025]

1 14V  
2 25V  
3 34V  
4 V  

Ans.

Using V=E(d)

V = E(10)

VAB=E.4=V10×4=2V5
