A spherical conductor `A` contains two spherical cavities as shown in Fig.2.127. The total charge on conductor itself is zero . However , there is a point charge `q_(1)` at the center of one cavity and `q_(2)` at the center of the other cavity . Another charge `q_(3)` is placed at a large distance `r` from the center of the spherical conductor.

If `q_(1)` is displaced from its center slightly (being always inside the same cavity ), then the correct representation of field lines inside the same cavity is

A

`F_1ltF_2ltF_3`

B

`F_1=F_2ltF_3`

C

`F_1=F_2gtF_3`

D

`F_1gtF_2gtF_3`

Text Solution

Verified by Experts

The correct Answer is:
B
`F_(3)-(K(a_(b)+q_(d)))/(r^(2))`
