A gang capacitor is formed by interlocking a number of plates as shown in figure. The distance between the consecutive plates is 0.885 cm annd the overlapping area of the plates is 5 `cm^(2)`. The capacity of the unit is

A

`1.0`

B

4 pF

C

6.36 pF

D

12.72 pF

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(eq)=(8Aepsilon_0)/(d)=(8xx5 xx10^(-4)xx8.85 xx10^(-12))/(0.885xx10^(-2))`
= 4pF
