## What is the angle between the equipotential surface and electric field at that point?

The angle between the electric field and the equipotential surface is always **90 ^{}**. The equipotential surface is always perpendicular to the electric field.

## When equipotential lines are traced to be closer the rate of loss of head will be?

If the equipotential lines are traced closer, then the loss of head is **fast and vice versa**. 6.

## Why electric field is always at right angles to equipotential surface?

this is because **there is no potential gradient along any direction parallel to the surface** , and so no electric field parallel to the surface. This means that the electric lines of force are always at right angle to the equipotential surface.

## What is the angle between electric field and magnetic field?

It is well known that light is transverse wave and the angle between the electric field and magnetic field is **90 degree for all light**.

## What is the angle between electric field and dipole moment at an equatorial point?

On equatorial line, the direction of electric field is reversed to that of angle of axial line. Therefore, the angle between dipole moment and electric field is **180°**.

## What is the angle between the direction of electric field at any axial point?

The angle between the direction of electric field at any axial point and equatorial point due an electric dipole is **180∘**.

## What is the general relation between electric field and potential?

The relationship between potential and field (E) is a differential: electric field is **the gradient of potential (V) in the x direction**. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.

## Is true for electric lines force?

The statement is **true** because tangent in the path of electric field lines gives us the direction of the electric field at that point. In case the lines cut each other, it means that there will be 2 directions on the electric field, which is impossible.
