A parallel plate capacitor of plate area...

A parallel plate capacitor of plate area `A = 600 cm^(2)` and plate separation d = 2.0 mm. is connected to a d.c. source of 200 V.
What is the charge density `sigma` on any one of the two plates?

A

`sigma = 8.85 xx 10^(-7) C//m^(2)`

B

`sigma = 8.85 xx10^(-9)C//m^(2)`

C

`sigma = 4.45 xx10^(-7) C//m^(2)`

D

`sigma = 4.45 xx10^(-9)C//m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
` 8.05 xx 10^(-7) c//m^(2)`
Explanation : `E = sigma/(epsilon_(0))`
` :. " " sigma=E epsilon_(0)`
`= 10^(5) xx 8, 85 xx10^(-12) = 8.85 xx10^(-7) c//m^(2)`
