Question

Eight dipoles of charges of magnitude e each are placed inside a cube. The total electric flux coming out of the cube will be ______. 

विकल्प

• `(8"e")/epsilon_0`

• `(16"e")/epsilon_0`

• `"e"/epsilon_0`

• zero

Answer 1

Eight dipoles of charges of magnitude e each are placed inside a cube. The total electric flux coming out of the cube will be zero.

Explanation:

Total flux is total field lines passing through any closed area

 Φ = `Sigma_"q"/Sigma_0`

ie, net charge on dipole is zero.
