At the midpoint of the line joining two equal point charges, the field is zero, and the electric field lines on this line joining the charges each begin at a charge and kind of end at the midpoint.

## What is electric potential at the midpoint of the line joining two equal and opposite charges?

The potential between two opposite and equal charges is zero because you make it zero by choosing the center point on a continuum.

## What is the potential at the midpoint between the 2 charges?

A point between two charges has an electric potential of zero, but a charge placed at this point will gain kinetic energy. Why? If I have a positive charge of +q and a negative charge of -q that are set a distance of r apart from each other, their midpoint will have an electric potential of zero.

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

The electric field intensity at a point on the line joining two point charges is zero.

## How do you find the electric potential between two charges?

The equation for the electric potential due to a point charge is V=kQr V = kQ r , where k is a constant equal to 9.0×10^{9} N⋅m^{2}/C^{2}.

## What is the electric potential between two positive charges?

Potential at any point due to a charge is proportional to its magnitude and inversely proportional to distance from the point charge. For two positive charges the two potential would add. Now as you move from one charge to another, the value of sum of inverse of the distances from their centres decreases.

## What is the electric potential at the midpoint?

At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

## What will be the electric field at the mid point of the line joining the two identical positive point charges what about electric potential?

At the midpoint of the line joining two equal point charges, the field is zero, and the electric field lines on this line joining the charges each begin at a charge and kind of end at the midpoint.

## What is the electric field at the midpoint?

Therefore, the electric field at mid-point O is 5.4 × 10^{6} N C^{−}^{1} along OB. (b) A test charge of amount 1.5 × 10^{−}^{9} C is placed at mid-point O. The force is directed along line OA. This is because the negative test charge is repelled by the charge placed at point B but attracted towards point A.
