## What is electric field at midpoint?

Resultant Electric field at mid-point-E= Since the net electric field is acting in opposite direction we have **E= 1440**. **= /C**. b) Let point P be on the line joining the charges such that it is 0.05m away from q_{2} and 0.15 m away from q_{1}_{.}

## What is the electric field at the midpoint of a dipole?

In the middle of the dipole, the electric fields contributed by both charges are in the same direction; they are **both pointing toward the negative charge**. Thus, the magnitude of the electric field is the sum of the contribution of the two charges.

## What is the electric field at the midpoint of the line joining two charges?

O is the mid-point of line AB. Therefore, the electric field at mid-point O is **5.4 × 10 ^{6} N C^{−}^{1} along OB**.

## What is the formula for electric field strength?

The SI unit of electric field strength is newtons per coulomb (N/C) or volts per meter (V/m). The force experienced by a very small test charge q placed in a field E in a vacuum is given by **E = F/q**, where F is the force experienced.

## Where is the electric field zero between two opposite charges?

The only place where the field vectors may point in absolutely opposite directions is **the line running between the two-point charges**. Hence the zero-field position must be there. The field vectors from both charges point toward the negative charge, thus it can’t be between the two opposite charges.

## Where is the electric field zero in a dipole?

In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In **Region III, the fields again point in opposite directions** and there is a point where their magnitudes are the same. It is at this point where the net electric field is zero.

## What is the direction of electric field in a dipole?

It is known that the direction of the electric field is from **the positive charge to the negative charge** and also that the direction of the dipole moment for a given dipole is from the negative charge towards the positive charge.

## Why is the electric field zero inside a charged conductor?

Electric field is zero inside a charged conductor. For a charged conductor, the charges will lie on the surface of the conductor.So, **there will not be any charges inside the conductor**. When there is no charge there will not be electric field.
