A right circular imaginary cone is shown...

A right circular imaginary cone is shown in figure A, B, and C are the points in the plane containing the base of the cone, while D is the point at the vertex of the cone. If `phi_A, phi_B, phi_C and phi_D` represent the fulx through the curved surface of the cone when a point charge Q is at points A, B, C, and D. respectively. then.

A

`phi_A = phi_C!=0`

B

`phi_D!=0`

C

`phi_B = Q/(2epsilon_0)`

D

`phi_A = phi_C = phi_D = 0`

Text Solution

Verified by Experts

The correct Answer is:
C, D
Flux through curved surface will be zero when charge is placed at `A , C , or D`. When charge is placed at `B`, flux through curved surface will be `Q//2 epsilon_(0)`.
