Electric Dipole

Step 1: Concept of electric flux.
Electric flux through a closed surface is given by Gauss's law: where: - is the charge enclosed by the surface, - is the permittivity of free space. Step 2: Electric flux from dipoles.
For an arrangement of electric dipoles, the net charge enclosed inside a closed surface is zero because the dipoles have equal and opposite charges that cancel each other out.
Step 3: Conclusion.
Thus, the electric flux coming out from the closed surface will be zero.

Step 1: Formula for electric dipole moment.
The electric dipole moment ( ) is given by the formula: where: - is the charge - is the separation distance between the charges. Step 2: Given values.
Given: - - Substitute the values into the formula: Step 3: Conclusion.
Thus, the electric dipole moment is .
