The distance between the plates of a charged parallel plate copacitor is `5cm` and electric field inside the plates is `200V cm^(-1)`. An uncharged metal bar of width `2 cm` is fully immersed into the capacitor. The length of the metal bar is same as that of plate of capacitor. The voltage across capacitor after the immersion of the bar is-

A

zero

B

`400 V`

C

`600 V`

D

`100 V`

Text Solution

Verified by Experts

The correct Answer is:
C
`V = E (d-t) = 20 xx (5-2) = 600V`
