An elliptical cavity is carved with in a prefect conductor figure. A positive charge q is placed at the center of the cavity. The points A and B are on the cavity surface as shown in the figure. Then

A

electric field near A in the cavity = electric field near B in the cavity

B

charge density at A = charge density at B

C

potential at A = potential at B

D

total electric field flux through the surface of the cavity is `q//epsilon_(0)`

Text Solution

Verified by Experts

All the points which lie on the conductor are at the same potential
Again, according the Gauss' law, net flux through the surface of cavity = `(q)/(epsilon_(0))`
