Question

Eight dipoles are placed at the centre of sphere.The net flux through the square is.
Options:-
1) 8Q/€
2) Q/8€
3) Q/€
4) none
Which one is the correct option..... ​

Answer 1

Answer:

A dipole consist of two charges q and −q, where is any charge.

Hence, net charge of a dipole is 0.

Hence, when 8 dipoles are kept inside a cube the net charge q

net

inside the cube is 0.

And, flux ϕ=

ϵ

o

q

net

⟹ϕ=0
