The electric dipole moment, in the case of a simple electric dipole, points from the negative charge to the positive charge and has a magnitude equal to the strength of each charge multiplied by the distance between the charges. Using the equation, we can calculate the electric field created by a point charge.

## What will be the value of electric dipole at the Centre?

Answer: **Twice the electric field**.

## Is electric field a vector?

Electric field strength is **a vector quantity**; it has both magnitude and direction.

## Can electric field due to a dipole be zero?

Answer. If dipole moment p is zero, then E=0,but then there is no dipole which is simply defined as two equal and opposite point charges separated by finite distance. This is not possible and hence **field of a dipole is not zero**.

## At what position is the electric field zero?

For unlike charges, the electric field is **zero outside of the smaller magnitude charge**. For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges.

## Can electric field be negative?

**Electric field is not negative**. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
