Two large thin conducting plates with a ...

Two large thin conducting plates with a small gap in between are placed in a uniform electric field E (perpendicular to the plates.)The area of each plate is A, and charges `+Q and -Q` are given to these plates as shown in figure. If R,S, and T are three points in space, then the

A

field at point R is E

B

field at point S is E

C

field at point T is `(E+Q/(Aepsilon_0))`

D

field at point S is `(E+Q/(Aepsilon_0))`

Text Solution

Verified by Experts

The correct Answer is:
A, D
At `R , E_(n et) = E + (Q)/( 2 A epsilon_(0)) - (Q)/( 2 A epsilon_(0)) = E`
At `S , E_(n et) = E + (Q)/( 2 A epsilon_(0)) + (Q)/( 2 A epsilon_(0)) = E + (Q)/( A epsilon_(0))`
At `T , E_( n et) = E + (Q)/( 2 A epsilon _(0)) - (Q)/( 2 A epsilon_(0)) = E`
