At what position or positions on the x-axis is the electric field zero?

The electric field will be zero at x = ± ∞.

Explanation:

Suppose, A -2.0 nC charge and a +2.0 nC charge are located on the x-axis at x = -1.0 cm and x = +1.0 cm respectively.

We know that,

The electric field is

The electric field vector due to charge one

The electric field vector due to charge second

We need to calculate the electric field

Using formula of net electric field

Put the value into the formula

Put the value into the formula

If x = ∞, then the equation is be satisfied.

Hence, The electric field will be zero at x = ± ∞.
